[Haskell-beginners] ghc problem

[jean verdier]

Trying to compile sources gives me:

ghc: internal error: evacuate(static): strange closure type 34
    (GHC version 6.10.4 for i386_unknown_linux)
    Please report this as a GHC bug:
http://www.haskell.org/ghc/reportabug

This already occured to me some times before and a cleanup and recompile
would work. This time i am stuck as i can't compile anymore. The ghc
version i use is the 6.10.4 from the ghc home page binary distribution i
think.

uname -a gives :
Linux localhost.localdomain 2.6.29.4-167.fc11.i586 #1 SMP Wed May 27
17:14:37 EDT 2009 i686 athlon i386 GNU/Linux

The command line is:
ghc  -fwarn-incomplete-patterns -fno-warn-unused-binds
-fno-warn-unused-matches -fno-warn-unused-imports
-fno-warn-missing-signatures -fno-glasgow-exts -Werror
-outputdir /tmp/mfk/build -package ghc  -i/tmp/mfk/gensrc --make
common/MFK/Common/SrcGen.hs common/MFK/Common/Conf.hs 

Any hints ?
