DamageArray related problems are fixed in these commits: https://github.com/spring/spring/commit/b6ea4915c9ab365910ba12501f988034f5a5f1ec https://github.com/spring/spring/commit/46a073e78f5c3092b0a59cb05e10adb5732ce066 good find abma!! :-) (and yes you were right, DamageArray was used when it was already freed) not really important: about all the ones with inflateReset2 in zlib: it is a zlib error, as can be seen here: http://www.zlib.net/ChangeLog.txt fixed in zlib 1.2.3.7 (24 Jan 2010) you may want to use valgrind suppressions for stuff that happens in the libraries (like opengl, devil (stuff starting with il*), zlib and the like)), though the suppression system is not so straight forward, and badly documented. maybe there are useful GUI tools for that. |

i tested with cppcheck from github, and it is not able to detect the issue we had here with DamageArray. so i made a simple test-case and reported it as a feature request: https://sourceforge.net/apps/trac/cppcheck/ticket/2957 |

then one issue is left: (others seem to be "only" mem-leaks) ==4052== Invalid read of size 8 ==4052== at 0x6B64337: __GI___strncasecmp_l (strcmp.S:215) ==4052== by 0x6B1AFAE: ____strtod_l_internal (strtod_l.c:577) ==4052== by 0x115954F: luaO_str2d(char const*, float*) (lobject.cpp:92) ==4052== by 0x11652E3: luaV_tonumber(lua_TValue const*, lua_TValue*) (lvm.cpp:41) ==4052== by 0x1149BA6: lua_isnumber(lua_State*, int) (lapi.cpp:264) ==4052== by 0xBD4F20: CLuaHandle::SendToUnsynced(lua_State*) (LuaHandle.cpp:337) ==4052== by 0x1153588: luaD_precall(lua_State*, lua_TValue*, int) (ldo.cpp:319) ==4052== by 0x116824C: luaV_execute(lua_State*, int) (lvm.cpp:612) ==4052== by 0x115385C: luaD_call(lua_State*, lua_TValue*, int) (ldo.cpp:377) ==4052== by 0x114B209: f_call(lua_State*, void*) (lapi.cpp:812) ==4052== by 0x11528BC: luaD_rawrunprotected(lua_State*, void (*)(lua_State*, void*), void*) (ldo.cpp:116) ==4052== by 0x1153C72: luaD_pcall(lua_State*, void (*)(lua_State*, void*), void*, long, long) (ldo.cpp:463) ==4052== Address 0x2104f0a0 is 32 bytes inside a block of size 38 alloc'd ==4052== at 0x4C28FAC: malloc (vg_replace_malloc.c:236) ==4052== by 0x4C29026: realloc (vg_replace_malloc.c:525) ==4052== by 0x114D60B: l_alloc(void*, void*, unsigned long, unsigned long) (lauxlib.cpp:635) ==4052== by 0x1159366: luaM_realloc_(lua_State*, void*, unsigned long, unsigned long) (lmem.cpp:82) ==4052== by 0x115EFB5: newlstr(lua_State*, char const*, unsigned long, unsigned int) (lstring.cpp:56) ==4052== by 0x115F33F: luaS_newlstr(lua_State*, char const*, unsigned long) (lstring.cpp:122) ==4052== by 0x116BBC9: luaX_newstring(LexState*, char const*, unsigned long) (llex.cpp:119) ==4052== by 0x116CA8F: read_string(LexState*, int, SemInfo*) (llex.cpp:330) ==4052== by 0x116D056: llex(LexState*, SemInfo*) (llex.cpp:393) ==4052== by 0x116D3AF: luaX_next(LexState*) (llex.cpp:455) ==4052== by 0x115C7CB: funcargs(LexState*, expdesc*) (lparser.cpp:618) ==4052== by 0x115CB09: primaryexp(LexState*, expdesc*) (lparser.cpp:718) shouldn't it be an < instead of <= https://github.com/spring/spring/blob/master/rts/Lua/LuaHandle.cpp#L335 [^] ?
