0001100: SIGSEGV on attempt to start new map with rev2942

Notes
(0003082) douggie_m (reporter) 2012-09-29 08:57	"on attempt to start new game", of course, I don't even get a list of maps (can't edit submitted issue). When I did /usr/share/vcmi/Maps# mv Step\ by\ Step.h3m ../ I got the following: Program received signal SIGSEGV, Segmentation fault.

I suppose I should upload my Maps directory contents. Also, I forgot backtrace: (gdb) s std::_Tuple_impl<0u, CInputStream, std::default_delete<CInputStream> >::_M_head (this=0xf2b53d78) at /usr/include/c++/4.7/tuple:152 152 const _Head& _M_head() const { return _Base::_M_head(); } (gdb) s std::_Head_base<0u, CInputStream, false>::_M_head (this=0xf2b53d78) at /usr/include/c++/4.7/tuple:104 104 const _Head& _M_head() const { return _M_head_impl; } (gdb) s std::unique_ptr<CInputStream, std::default_delete<CInputStream> >::operator-> (this=0xf2b53d78) at /usr/include/c++/4.7/bits/unique_ptr.h:213 213 } (gdb) s Program received signal SIGSEGV, Segmentation fault. 0x1054c41c in SelectionTab::parseMaps (this=0x1158ad58, files=..., start=0, threads=1) at CPreGame.cpp:1052 1052 int read = stream->read(mapBuffer, 1500); (gdb) bt #0 0x1054c41c in SelectionTab::parseMaps (this=0x1158ad58, files=..., start=0, threads=1) at CPreGame.cpp:1052 #1 0x1054d274 in SelectionTab::SelectionTab(CMenuScreen::EState, const boost::function<void(CMapInfo)> &, CMenuScreen::EMultiMode) (this=0x1158ad58, Type=CMenuScreen::newGame, OnSelect=..., MultiPlayer=CMenuScreen::SINGLE_PLAYER) at CPreGame.cpp:1143 0000002 0x1054889c in CSelectionScreen::CSelectionScreen (this=0x11547358, Type=CMenuScreen::newGame, MultiPlayer=CMenuScreen::SINGLE_PLAYER, Names=0x0) at CPreGame.cpp:599 0000003 0x105474a0 in CGPreGame::openSel (this=0xec100fb8, screenType=CMenuScreen::newGame, multi=CMenuScreen::SINGLE_PLAYER) at CPreGame.cpp:455 0000004 0x105abf24 in boost::_mfi::mf2<void, CGPreGame, CMenuScreen::EState, CMenuScreen::EMultiMode>::operator() (this=0x10b09360, p=0xec100fb8, a1=CMenuScreen::newGame, a2=CMenuScreen::SINGLE_PLAYER) at /usr/include/boost/bind/mem_fn_template.hpp:280 0000005 0x105a3da0 in boost::_bi::list3<boost::_bi::value<CGPreGame>, boost::_bi::value<CMenuScreen::EState>, boost::_bi::value<CMenuScreen::EMultiMode> >::operator()<boost::_mfi::mf2<void, CGPreGame, CMenuScreen::EState, CMenuScreen::EMultiMode>, boost::_bi::list0> (this=0x10b09368, f=..., a=...) at /usr/include/boost/bind/bind.hpp:392 0000006 0x10599428 in boost::_bi::bind_t<void, boost::_mfi::mf2<void, CGPreGame, CMenuScreen::EState, CMenuScreen::EMultiMode>, boost::_bi::list3<boost::_bi::value<CGPreGame>, boost::_bi::value<CMenuScreen::EState>, boost::_bi::value<CMenuScreen::EMultiMode> > >::operator() (this=0x10b09360) at /usr/include/boost/bind/bind_template.hpp:20 0000007 0x1058bcfc in boost::detail::function::void_function_obj_invoker0<boost::_bi::bind_t<void, boost::_mfi::mf2<void, CGPreGame, CMenuScreen::EState, CMenuScreen::EMultiMode>, boost::_bi::list3<boost::_bi::value<CGPreGame>, boost::_bi::value<CMenuScreen::EState>, boost::_bi::value<CMenuScreen::EMultiMode> > >, void>::invoke (function_obj_ptr=...) at /usr/include/boost/function/function_template.hpp:153 0000008 0x10267d3c in boost::function0<void>::operator() (this=0x108fe9a8) at /usr/include/boost/function/function_template.hpp:760 0000009 0x10268190 in CFunctionList<void ()>::operator()() const (this=0x11519a4c) at ./UIFramework/../FunctionList.h:62 0000010 0x10255bbc in CAdventureMapButton::clickLeft (this=0x115199f0, down=..., previousState=true) at ./UIFramework/CIntObjectClasses.cpp:335 0000011 0x10244024 in CGuiHandler::handleEvent (this=0x108e0444, sEvent=0xf2b54b98) at ./UIFramework/CGuiHandler.cpp:247 0000012 0x10243264 in CGuiHandler::handleEvents (this=0x108e0444) at ./UIFramework/CGuiHandler.cpp:140 0000013 0x10547bd8 in CGPreGame::update (this=0xec100fb8) at CPreGame.cpp:496 0000014 0x10244ca4 in CGuiHandler::run (this=0x108e0444) at ./UIFramework/CGuiHandler.cpp:348 0000015 0x104d3d0c in boost::_mfi::mf0<void, CGuiHandler>::operator() (this=0xec149974, t=...) at /usr/include/boost/bind/mem_fn_template.hpp:70 0000016 0x104d3a64 in boost::_bi::list1<boost::reference_wrapper<CGuiHandler> >::operator()<boost::_mfi::mf0<void, CGuiHandler>, boost::_bi::list0> (this=0xec14997c, f=..., a=...) at /usr/include/boost/bind/bind.hpp:253 0000017 0x104d3934 in boost::_bi::bind_t<void, boost::_mfi::mf0<void, CGuiHandler>, boost::_bi::list1<boost::reference_wrapper<CGuiHandler> > >::operator() (this=0xec149974) at /usr/include/boost/bind/bind_template.hpp:20 0000018 0x104d3060 in boost::detail::thread_data<boost::_bi::bind_t<void, boost::_mfi::mf0<void, CGuiHandler>, boost::_bi::list1<boost::reference_wrapper<CGuiHandler> > > >::run (this=0xec149870) at /usr/include/boost/thread/detail/thread.hpp:62 0000019 0x0e2cf40c in ??

(0003085) Ivan (developer) 2012-09-29 09:21	With your maps crash is reproducible. Will check what's wrong.

(0003087) Ivan (developer) 2012-09-29 09:23	Myth and legends.h3m causes crash. Removing this file should fix this. Now I need to figure out why VCMI can't load it...

(0003089) douggie_m (reporter) 2012-09-29 09:28 edited on: 2012-09-29 09:36	Not on my side. I did /usr/share/vcmi# mv Maps/myth\ and\ legend.h3m Maps\ $Disabled$/ And still got SIGSEGV (with all other maps kept), mapBuffer is still the same as in topic post: (gdb) p mapBuffer $1 = "\025\000\000\000\001H\000\000\000\001\f\000\000\000Step by Step\214\000\000\000A harsh winter has separated what once was your kingdom. Now that the winter is over, it is time to take your kingdom back, step by step. \001\000\001\001\000\377\001\001\001\001\377\003\a\000\000\377\000\000\000\000\000\001\001\000\377\001\001\001\001\377\003\005\001\000\377\000\000\000\000\000"... UPD: By the way, myth\ and\ legend.h3m is from LOKI, but gzipped manually by myself some time ago.

(0003090) Ivan (developer) 2012-09-29 09:33	You moved it into subdirectory? Right now VCMI will parse all subdirectories as well so this map still will be parsed and will crash again.

(0003091) douggie_m (reporter) 2012-09-29 09:36	No, 'Maps (Disabled)' is in /usr/share/vcmi as well as 'Maps', and not in a subdir of Maps.

(0003092) Ivan (developer) 2012-09-29 09:44	Ah. Too many slashes. FYI - typing " before file name won't broke autocomplete and will give more readable commands. Check rev 2947 - it should fix loading of myth and legends and will print file name of broken map

(0003093) douggie_m (reporter) 2012-09-29 09:48 edited on: 2012-09-29 09:55	Maybe 'all for one.h3m' is the cause (maybe because it is uncompressed). When it is used with any other gzipped map. /usr/share/vcmi# ls -l Maps total 144 -rw-rw-r-- 1 root root 130076 Sep 20 14:04 all for one.h3m -rw-rw-r-- 1 root root 16092 Aug 11 12:25 ascension.h3m Segfaults too. But the same 'all for one.h3m' left alone together with 'VCMI_Tests_2011b.h3m' loads perfectly. UPD: no, moving out 'all for one.h3m' together with 'myth and legend.h3m' doesn't help. It's magic.

(0003094) douggie_m (reporter) 2012-09-29 09:49	Will check rev2947.

(0003096) douggie_m (reporter) 2012-09-29 10:24	With rev2947, issue is resolved fixed.
