This is perplexing me:

Sometimes, programs I compile with DJGPP crash every time they open a
file.  In almost every case, the problem somehow disappears if I touch
the source and recompile with the same options.  

The crash (when I've been able to trace it) leads into and slightly
beyond fopen().  However, it more often just goes into an infinite loop
I can't escape from (that particular program replaces the keyboard
handler).  In these cases, the crash seems to occur sometimes at fopen()
an sometimes with findfirst() or findnext().

I haven't been able to purposely recreate the problem, though; and I
have only been able to catch the callback frame a few times.  If anyone
knows why this might possibly happen, I'd like to know -- but otherwise
I'll try to find a way to recreate the problem so it occurs in a
predictable manner.
