#3060: impossible internal bug while building darcs
-------------------------+--------------------------------------------------
Reporter: quick | Owner:
Type: bug | Status: new
Priority: normal | Milestone:
Component: Compiler | Version: 6.10.1
Severity: major | Resolution:
Keywords: | Difficulty: Unknown
Testcase: | Os: Linux
Architecture: x86 |
-------------------------+--------------------------------------------------
Comment (by quick):
This is a clean directory using the config/make build.
It appears to be related to optimization:
$ rm src/Exec.o
$ ghc -dcore-lint -I. -I./src -I./src -i./src -c src/Exec.hs
$ rm src/Exec.o
$ ghc -dcore-lint -I. -I./src -I./src -i./src -c -O2 src/Exec.hs
ghc: panic! (the 'impossible' happened)
(GHC version 6.10.1 for i386-unknown-linux):

Also note that the -dcore-lint doesn't seem to have any effect.
Let me know if there's anything else I can provide.
