Any ideas ?
It sometimes happens, sometimes not...

Marked line jumps to this ...

#SelectExpand
  1void TMenuItem::ProcessMouseEvent(ALLEGRO_MOUSE_EVENT * mouse_event)
  2{
  if ((mouse_event->x > m_nX) &&
      (mouse_event->x < m_nX + m_nWidth) &&
      (mouse_event->y > m_nY) &&
      (mouse_event->y < m_nY + m_nHeight))
  {
      m_blHighlight = true;
      if ((m_pCallBack!=NULL)&&(mouse_event->button == 1))
      {
          m_pCallBack();
      }
  }
  else
  {
     //TODO (Anyone #1#): when clicking a menu item sometimes this generates an annoying segmentation fault
      m_blHighlight = false;
  }
 19}

And this causes a segmentation fault

Where is the ALLEGRO_MOUSE_EVENT allocated?

It appears that your mouse event is bad. Either you didn't allocate it and its uninitialized, or you destroyed it and didn't set it to zero.

The address stored in mouse_event seems off.

King Piccolo will make it so Then I could just flip it with some sweet, sweet matrix math. In either case, I’ll ride this wagon until the wheels fall off. Thanks to those that keep it running

The address seems close to argv. Could that just be where the globals are allocated? shrug

Is there any threading shenanigans going on?

I mean the best with what I say. It doesn't always sound that way.

I was deleting and rebuilding the menu at some point..
It might be that an event was fired while the menu was gone.. ( not sure) but I changed it to just clearing and adding new menu items.. and the problem seems to be gone..
I hope it stays that way...
