Hi,
We are using LUA in our current game, but we are currently
experiencing horrible memory leaks with it. We did modify the lua
code slightly(actually just the lstate.h) file where I added a couple
of pointers..
<---Code changes to lstate.h--->
{Rest of lua_State struct up here}
lua_Hook callhook;
lua_Hook linehook;
int allowhooks;
/* Additional Pointer reference for class. Added by Terence */
void * pMemory; /* Access to Memory subsystem */
void * pComms; /* Access to Communicatin subsystem */
void * pEvent; /* Access to Event Sub-System */
void * pAI; /* Access to AI Sub-System */
void * pScene; /* Access to scene management subsystem */
void * pLog; /* Access to central error logger(for debug) */
void * pProc; /* ProcMgr */
unsigned long dwCharID;
unsigned short wEventID;
void * pData;
void * pSendThread;
void * pTaskMgr;
};
<--------Done----->
I have tried:
1) Calling collectgarbage(0) at all return points in scripts
2) I tried reseting the stack to its original position by calling
lua_gettop(L) and then call lua_dobuffer() and then call lua_settop
3) I tried call lua_setgcthreshold(L,0) after a lua_dobuffer() has
been run
4) I have even recompiled it using the g++ compiler
5) I have integrate and replaced lmem.c realloc with dalloc(as stated
in one of the lua wiki's)
And its still leaks..
My questions(some are pretty silly showing how desperate I am)
1. As anybody else had any problems running this.. I am calling a lua
script pretty often..it's a game after all..
2. would compiling it in debug mode or running gdb with it cause any
issues
3. Is is possible to re-write lmem.c to put use a static set pool of
memory instead of a rapid growing one..
4. Do to many calls to lua_newtable( always check that I pop it off
and try to keep the stack state every time I call my API's) or
anything contribute to the leak..what should I look at...(more
specifically which API's or what can cause leaks
Sorry bout the long post.

PS..when I try to call lua_close..the entire app segmentation
faults... with the following code
Program received signal SIGSEGV, Segmentation fault.

I am using LUA4.0(I tried 4.1 work4) and it has the same problem.
