Child window with ALLEGRO_MENU causes crash upon open/close display.

[MatiasMunk]

Using the ex_menu.c example in a program.
The program will crash, if you open/close the child window multiple times.

This is a problem, since I'm developing a game where you can open editor windows for e.g. maps, items, etc.

Crash upon close is in 'allegro5/platform/aintwthr.h' line 59

AL_INLINE(void, _al_mutex_lock, (struct _AL_MUTEX *m),
{
   if (m->cs)
      EnterCriticalSection(m->cs);
})

Crash upon open is in 'allegro/src/win/wwindow.c' line 196
GetWindowInfo(my_window, &wi);
and sometimes other places, like allegro/src/memory.c line 44

/* Function: al_malloc_with_context
 */
void *al_malloc_with_context(size_t n,
   int line, const char *file, const char *func)
{
   if (mem)
      return mem->mi_malloc(n, line, file, func);
   else
      return malloc(n); //This right here line 44
}

I hope I'm not wrong.

For work with the menu in the Windows system, a ./addons/native_dialog/win_menu.c is needed.

I can't work with Windows so I can't check either.

EDIT: You have to ask for a new feature, I guess.

win_menu.c is non-existant in the source.
It's not that menu doesn't work. It does. It's just that the program crashes when you close and open the window again. I suspect some mutex lock mistake or forgetting to release some memory. Idk.
