Great, that's gonna be no problem.

Concerning your original instructions:

 | Please compile the program with -debug, then open it with
 | gdb. Set a breakpoint on barf() and run the program:
 |
 | gdb> break barf
 | gdb> run
 |
 | and wait for it to hit the breakpoint.  Then do
 |
 | gdb> signal SIGABRT
 |
 | to get a core dump. Send the source, binary, and core
 | dump to us. With any luck, we'll be able to track it down
 | without running the program.

I'll wait for the bug to occur again, before I'll do that,
okay? My GHC version was several weeks old, perhaps the bug
is gone (or looks different) in the most current GHC.

Thanks for the help!
