Application Verifier indicates an error

[Shmuel Zeigerman <shmuz@...>]

[Windows XP SP3 32 bit, Lua 5.1 and 5.2]

Running various Lua binding DLLs with Microsoft Application Verifier, I 
noticed that all bindings that are C++ give an error. The error message 
is: "Unloading DLL that allocated TLS index that was not freed."

Both Lua and the libraries were built with MinGW 4.5.2.
Here is a simple example that reproduces the error.

/* mylib.cpp */
extern "C" {
#include <lua.h>
}

extern "C" __declspec(dllexport)
int luaopen_mylib (lua_State *L)
{
  char* buf = new char;
  delete buf;
  return 0;
}

-- test.lua
require "mylib"
print "OK" --> it prints OK

Here is the log of Application Verifier:
