---------- Forwarded message ---------- From: 吴兴博 Date: 2011/6/5 Subject: Abnormal behaviors when Using ghci To: cvs-ghc@haskell.org 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? :-) regards! -- ---------------- 吴兴博  Wu Xingbo
