This question was probably answered before but I ran into a problem
trying to push many lua values from a c function.
This is a small application that shows the problem.
extern "C"
{
#include "lua-5.1.4/src/lua.h"
#include "lua-5.1.4/src/lauxlib.h"
}
void main()
{
lua_State * state = luaL_newstate();
for(size_t i = 0; i< 50; ++i)
{
//lua_checkstack(state, 1); // Uncommenting this "fixes" the problem.
lua_pushnumber(state, 7.0);
}
lua_close(state);
}
Upon "lua_close" the program crash (Heap corruption).
I am compiling under windows.
Can anyone help me understand what the problem is?
iirc, the "standard" Lua stack has a depth of 20. You are using 50
entries. You should ensure you have enough space by calling lua_settop.
Thank you,
