odd segfault with my c program using cygwin 1.7

  Still, it could be some other overflow somewhere else; as I'd guess you were
reasoning, that's the commonest reason for this sort of bug that crops up on
some platforms with some stack and memory layouts and not others.

   Jeff, recompile your code, adding the "-g" flag, then run it under gdb, and
when the segfault happens, use the "bt" command to get a backtrace and see
where you are.

     cheers,

It runs correctly under the debugger, without core dump.
I am 99.9% sure the bug is outside my program. As I said,
I have run it successfully with cygwin 1.5, and linux.

I cannot imagine commenting/uncommenting the print statement
changing the program execution. I suspect a library resource
issue causing the segfault.

As others have pointed out, I am pretty sure it is not going
out of bounds on the array.

thanks,
jeff
