Perhaps this is a related problem: Haskell programs compiled ghc-4.04
(or 4.05, I can't remember exactly) sometimes totally screw up the
communication between Bash and XEmacs in a shell buffer: Bash seems
to receive an infinite stream of char 255 (=> .bash_history grows
to dozens of Megs) after a Haskell program terminates. I've got no
idea why and when exactly this happens, but I hope somebody else has...
:-)
Cheers,
Sven
P.S.: tcsh seems to be immune against this problem.
