#2162: panic! (the 'impossible' happened) while compiling XMonadContrib
-----------------------+----------------------------------------------------
Reporter: ivant | Owner:
Type: bug | Status: new
Priority: normal | Component: Compiler
Version: 6.8.2 | Severity: normal
Keywords: | Testcase:
Architecture: x86 | Os: Unknown
-----------------------+----------------------------------------------------
I was rebuilding XMonadContrib without doing Cabal clean first. I got the
"panic!" message. The problem was persistent: if I started Cabal build
again, I was getting the same message. After I did Cabal clean followed by
Cabal build, the problem disappeared. Seem to be a problem with
interacting with previously compiled code.
Here is the output of GHC:
