Greetings. Ran into a bug with ghc 6.2 on some code that most probably
used to work. I'm using a newer version of the fgl, from what I was
using before, though. This only happens with -O2, and I don't think
-dcore-lint or -dppr-debug do anything interesting. It happens with or
without the heap-size flag. The usual problem with sharing Aetion code
applies here, so I can't send you the files. I'm glad to help track
this down in other ways, though.
/usr/bin/ghc --make -O2 -dcore-lint -dppr-debug -fwarn-name-shadowing
-fglasgow-exts -fwarn-incomplete-patterns -package lang -package data
-package fgl -H4564m -fallow-overlapping-instances -i/usr/lib/HUnit
-i/usr/lib/happy-1.13 -i/usr/lib/HUnit Main.hs
ghc-6.2: panic! (the `impossible' happened, GHC version 6.2):
