Got it once more. And I think I found source - deadlock, bit I still have no idea how to fix: Thread A (GuiHandler::run) stuck here: 3 0x00000000005a19b0 in vstd::unlock_guard<boost::recursive_mutex, vstd::detail::unlock_policy<boost::recursive_mutex> >::~unlock_guard ( this=0x7ff1ad731820, __in_chrg=<optimized out>) at /lib/UnlockGuard.h:72 4 0x0000000000776886 in CPlayerInterface::moveHero (this=0x7ff1a748e220, h= 0x7ff1a54e8920, path=...) at /client/CPlayerInterface.cpp:1254 Thread B (CClient::run) stuck here: 4 0x00007ff1bf4eacb7 in boost::unique_lock<boost::shared_mutex>::unique_lock (this=0x7ff1aa971c80, m_=...) at /usr/include/boost/thread/locks.hpp:290 5 0x00007ff1bf4d47e5 in CApplyOnGS<HeroVisit>::applyOnGS ( this=0x7ff1a5278520, gs=0x7ff1a5322ba0, pack=0x7ff1905859d0) at /home/ivan/src/vcmi/lib/CGameState.cpp:77 Any ideas how to fix? |

Fixed in r2698 by reordering locks. :/ Not very nice, it would be best if I had a lock that atomically locks two (heterogeneous) mutexes. Seems not effort-worthy for now. |
