I already made a program thta works just fine with the allegro library
(i think v.2.2? The newest version?), and loops in the following basic
way:
do
{
    ...
} while (!key[KEY_ESC])

I am making another program that also has that same looping structure.
I can hit escape and the program will terminate and call my shutdown
stuff/etc., but I noticed that allegro dumps this debug  stuff out to
the screen (telling me what the registers are/etc).  That's not the real
problem though.  The problem is that in the middle of that loop, i have
a statement that says
if (key[KEY_PGUP])
{
    ++count;
    ....
}
as soon as I hit page up, my program stops at the line ++count (without
executing it), and terminates with an error saying that allegro received
signal SIGSEGV and complaining of a general protectin fault.  I can't
see how this is really any different from my original progam, which also
detected key presses in the middle of the loop.  Anyone have any ideas?
