Very mysterious. I've never seen one of these without -dcore-lint
bleating first.
Suggestions:
1. Don't use --make, so you can be certain which module is involved.
2. On the module that breaks, add -verbose-core2-core -dppr-debug
-ddump-stg
and send us the output.

| Subject: impossible in ghc 6.2
|
| 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 I'm using a newer version of the fgl, from what I was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
