If I repeatedly execute the string "a=math.random(1,20)" in my embedded interpreter, when I stop the host I got a crash with a lot of glibc errors.

Perhaps you're overflowing the stack? It shouldn't happen. Can you post
code? A minimal example would help.
This is the code that executes the string
void ScriptEngine::exec(string str)
    if (str.length() > 0) {
int error = luaL_loadbuffer(luaVM, str.c_str(), str.length(), "line") || lua_pcall(luaVM, 0, 0, 0);
            if (error) {
                cout << lua_tostring(luaVM, -1) << endl;
                lua_pop(luaVM, 1);

In my code I simply do this, as a basic stress test:


If I replace the code by "math.random(1,20)" no problems occurs.

Overflowing the stack does not explain this.

Is there any way to destroy variables used in an script when I dont need them anymore?

Set them to nil, but you shouldn't have to do that.
