: Thank you

This error is really strange.

The piece of code looks like this:
--------------------------------------------------------
aaa () 
{
  (void) printf ("aaa has been called\n");
  some more stuff
}
main ()
{
 another more stuff
 (void) printf ("aaa will be called\n");   <------this works
 aaa();                                    <------and this no more 
 yet more stuff
}
--------------------------------------------------------
And the result:
aaa will be called
Exiting due to signal SIGFPE
Floating point exception at eip=0000176e

STRANGE !!!

And it happens on both 486 and on Pentium,
so PC hardware mulfunction is not probable.

Oh oh oh   :-(

Have you any idea what to do ?
