What happens if you call _exit(1) instead of exit(1) ?

The way to really understand this is to download the library sources, 
extract the source of the exit() function, and add some debugging 
print-outs there that will show where does it get stuck.  Then post the 
offending code fragment from exit() here, and someone will help you 
figure it out.

The most probable cause is some bug in your program, but the question is 
where is it?

Did you use any libraries, like Allegro?  If so, tell which ones you 
used, and what functions from there are you calling.
