Every once in awhile after closing this program it crashes when it gets to the destroy timer line - Ive had this happen in several other programs as well, its getting pretty annoying. 1//
2// main.cpp
3// Timer

I think swapping line 164 ("al_destroy_event_queue(event_queue)") and line 163 ("if(timer) al_destroy_timer(timer)") would fix it. In other words, the queue depends on the other stuff, and it's trying to access a destroyed timer, so always destroy the queue first. They all watch too much MSNBC... they get ideas. |

I think someone told me to do that before in a previous program but the problem still persisted. Ill let you know if it keeps crashing after switching them EDIT:Nope its still crashing |

Windows, I presume? Make a small test case and I'll look at it.

I don't have a Mac so unfortunately I can't test there. I did build and run your 611140 program on Linux but couldn't get it to crash. How often does it happen? Maybe someone else with a Mac could try it?
