During the compilation of a small project with ghc-3.01 (Linux) I get:
panic! (the `impossible' happened):
unboxArg: PrelBase.(){-40-}
The code leading to this error is available at:
http://www.pms.informatik.uni-muenchen.de/mitarbeiter/panne/impossible.tar.gz
Just type "make" and wonder... (Mesa is needed for this.)
If necessary , I can try to cut the example down tomorrow.
