GHCi says: ghc: internal error: evacuate: strange closure type 63587
Error:
The error message shown by GHCi to me:
ghc: internal error: evacuate: strange closure type 63587
(GHC version 6.12.3 for i386_unknown_linux)
Please report this as a GHC bug: http://www.haskell.org/ghc/reportabugI'm not sure whether this should be classified as GHCi or GHC the compiler, as I wasn't compiling anything at the time, but maybe something inside GHCi was.
This tends to happen on all my projects. I am unable to directly reproduce it. It is not a particularly big problem as Emacs automatically re-launches GHCi.
Background:
I use GHCi inside Emacs. I forward all my Cabal configure/build and any other Haskell-related scripts through GHCi with :! and all the output is forwarded back by GHCi. Maybe it is merely a GHCi bug in using commands? I only suspect this because I only recall getting bugs like this since I started doing this kind of forwarding -- I may be mistaken in that recollection.
For what it's worth, below I include a list of libraries used. But I don't suspect those to be the cause. I assume that the part of GHCi which runs the :! commands is small and self-contained, so I'll have a bash at testing/fixing that, or at least reproducing the error. I doubt many else use :! like I do.
