1) I'm using Haskell platform 2011.2 on windows (7). Every several
days, ghci will crash with no messages. even when I'm just typing with
text buffer, without an 'enter'. I got nothing after the crash, not
even an exception code, don't even mention the core-dump. Should I
report bugs with nothing to give, only "it crashes."? I think I should
be careful with sending messages.

2) do that:
open ghci.
 > :set -fbreak-on-exception
 > :trace [undefined]
then you catch a _exception
 > :print _exception
Then it prints a chaos... that's because the printing of the exception
contains too many white-spaces because of indent.
I think this can be some kind of malformed features. since It isn't a
bug, what 'type' should the problem be? :-)
