segv in ldo.c:line 284 for lua version 5.0

["Jiangwei Li" <jli@...>]

Hi, 

I got the following segv: it happened in vm 
post calling a c function.

I was wondering if this is caused by a known problem?

thanks,
Jiangwei



I was calling a script function call "AppMain"
in a loop, like this:

name: is the script file name
APPINITNAME: AppInit

  /* load the script "name" */
  status = report(l, luaL_loadfile(l, name) || lua_pcall(l, 0, 0, 0));
  if(status) { return status;}
  
  /* execute a script function called "AppInit" */
  lua_pushliteral(l, APPINITNAME); 
  lua_gettable(l, LUA_GLOBALSINDEX);
  status=report(l, lcall(l, 0, 1));
  if(status) { return status;}

  /* calling script function called "AppMain" in a loop 100x100 times*/
  for(iy=0; iy<100; iy++)  {
    for(ix=0; ix<100; ix++) {
      lua_pushliteral(l, APPMAINNAME); 
      lua_gettable(l, LUA_GLOBALSINDEX);
      status = report(l, lcall(l, 0, 1));
      if(status) {break;}
    }    
  }

Here is my setting:
