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.

Cheers,
        Simon
