ghc panic
ghc-6.8.3: panic! (the 'impossible' happened)
(GHC version 6.8.3 for powerpc-apple-darwin):
parser/Ctype.lhs:(91,13)-(347,35): Non-exhaustive patterns in case
I've been getting intermittent hangs or crashes from GHC such as the error message above. When I restart the build, it successfully compiles. I did not observe this for ghc 6.8.2 on intel. I only observe it for ghc 6.8.3 for ppc which I am running under the Rosetta JIT compiler in order to cross compile to ppc binaries from an intel macintosh.
