Description
I've been seeing somewhat frequent crashes in Ultima 6 using a version compiled from the master branch on git (529fdca7eaccd48be3f2e081164713106c9702b6) that do not 'appear' to be related to particular actions.
I am using archlinuxarm on an aarch64 system, running sway-wm.
I took a core dump, and included the backtrace below:
Core was generated by `scummvm'. Program terminated with signal SIGSEGV, Segmentation fault. #0 0x0000aaaab0a6be54 in Ultima::Nuvie::U6LList::start (this=0x7) at engines/ultima/nuvie/misc/u6_list.cpp:223 223 cur = head; [Current thread is 1 (Thread 0xffff908d55d0 (LWP 50713))] (gdb) bt #0 0x0000aaaab0a6be54 in Ultima::Nuvie::U6LList::start() (this=0x7) at engines/ultima/nuvie/misc/u6_list.cpp:223 #1 0x0000aaaab0a1f498 in Ultima::Nuvie::delete_obj(Ultima::Nuvie::Obj*) (obj=0xaaaac4e23bf0) at engines/ultima/nuvie/core/obj_manager.cpp:2037 #2 0x0000aaaab0a1f4c8 in Ultima::Nuvie::delete_obj(Ultima::Nuvie::Obj*) (obj=0xaaaac4a4a6f0) at engines/ultima/nuvie/core/obj_manager.cpp:2041 #3 0x0000aaaab0a846e4 in Ultima::Nuvie::nscript_obj_gc(lua_State*) (L=0xaaaac42d20d0) at engines/ultima/nuvie/script/script.cpp:1779 #4 0x0000aaaab1529930 in luaD_precall(lua_State*, lua_TValue*, int) (L=0xaaaac42d20d0, func=0xaaaac4e23bd0, nresults=0) at common/lua/ldo.cpp:344 #5 0x0000aaaab1529c24 in luaD_call(lua_State*, lua_TValue*, int) (L=0xaaaac42d20d0, func=0xaaaac4e23bd0, nResults=0) at common/lua/ldo.cpp:401 #6 0x0000aaaab152c500 in GCTM(lua_State*) (L=0xaaaac42d20d0) at common/lua/lgc.cpp:465 #7 0x0000aaaab152cb3c in singlestep(lua_State*) (L=0xaaaac42d20d0) at common/lua/lgc.cpp:592 #8 0x0000aaaab152cc0c in luaC_step(lua_State*) (L=0xaaaac42d20d0) at common/lua/lgc.cpp:615 #9 0x0000aaaab1523090 in lua_pushcclosure(lua_State*, int (*)(lua_State*), int) (L=0xaaaac42d20d0, fn=0xaaaab0a7f1e4 <Ultima::Nuvie::lua_error_handler(lua_State*)>, n=0) at common/lua/lapi.cpp:492 #10 0x0000aaaab0a83290 in Ultima::Nuvie::Script::call_function(char const*, int, int, bool) (this=0xaaaac472f6f0, func_name=0xaaaab1b8f730 "actor_int_adj", num_args=1, num_return=1, print_stacktrace=true) at engines/ultima/nuvie/script/script.cpp:1352 #11 0x0000aaaab0a827c8 in Ultima::Nuvie::Script::call_actor_int_adj(Ultima::Nuvie::Actor*) (this=0xaaaac472f6f0, actor=0xaaaac4cac820) at engines/ultima/nuvie/script/script.cpp:1177 #12 0x0000aaaab0ab3500 in Ultima::Nuvie::ActorView::display_actor_stats() (this=0xaaaac4802400) at engines/ultima/nuvie/views/actor_view.cpp:224 #13 0x0000aaaab0ab2a50 in Ultima::Nuvie::ActorView::Display(bool) (this=0xaaaac4802400, full_redraw=false) at engines/ultima/nuvie/views/actor_view.cpp:119 #14 0x0000aaaab0a37ecc in Ultima::Nuvie::GUI::Display() (this=0xaaaac441fb40) at engines/ultima/nuvie/gui/gui.cpp:192 #15 0x0000aaaab0a12314 in Ultima::Nuvie::Game::play() (this=0xaaaac3c43df0) at engines/ultima/nuvie/core/game.cpp:654 #16 0x0000aaaab09f4634 in Ultima::Nuvie::NuvieEngine::run() (this=0xaaaac4011160) at engines/ultima/nuvie/nuvie.cpp:179 #17 0x0000aaaaae6c5c28 in runGame(Plugin const*, OSystem&, Common::String const&) (plugin=0xaaaac36e9760, system=..., edebuglevels=...) at base/main.cpp:307 #18 0x0000aaaaae6c6d38 in scummvm_main(int, char const* const*) (argc=1, argv=0xffffc5b983d8) at base/main.cpp:594 #19 0x0000aaaaae6c351c in main(int, char**) (argc=1, argv=0xffffc5b983d8) at backends/platform/sdl/posix/posix-main.cpp:45

I ran U6 with address sanitizer for a while but didn't see any issues appear, it's quite possible this is already fixed - it's an old report and the code has seen a lot of fixes since then.
