This is a strange problem, that just popped up in my program:

My program will hang, when Allegro's install_mouse() is called. I looked at 
the sources, but I didn't see any possibilities for infinite loops. Could it 
be, that the locking of variables that is done inside install_mouse() somehow 
fails and this will produce the mentioned behavior?

Now, as if that weren't strange enough, this problem will not occur anytime 
install_mouse() is called, but only when I pass more than one argument to my 
program (i.e. argc>2).

I would post some code if I saw a way to chop my code down to the core of the 
problem, but it's simply to big and I don't expect a little test program to 
show that behavior. After all, install_mouse () has been working for years, no 
matter how many arguments I passed to my programs.

Btw: All the Allegro install and init routines are called after my program has 
been running for some time, thereby eating up some memory. Is there any 
reason to call these routines as soon as possible after program start?

I am using Allegro 3.11 with gcc version egcs-2.91.66 19990314 (egcs-1.1.2 
release) on Win95.

Any ideas anybody?
