---------------------+------------------------------------------------------
On a project here, we are building a custom version of ghc. Part of our
build process involves building the base library with Cabal, which
produces the following error message:
{{{
[ 57 of 128] Compiling Data.Either ( Data/Either.hs,
dist/build/Data/Either.o )
[ 58 of 128] Compiling System.IO.Error ( System/IO/Error.hs,
dist/build/System/IO/Error.o )

dist/build/Text/Read.o )
[ 60 of 128] Compiling Foreign.Ptr ( Foreign/Ptr.hs,
dist/build/Foreign/Ptr.o )
ghc: panic! (the 'impossible' happened)

The command that Cabal generated was this:

I noticed that if I remove the -O from the command that cabal generated,
and rebuild after cleaning and re-configuring, the problem goes away.
However, if I clean, reconfigure and use the command that Cabal generated,
I get the same build error.
This bug has been seen on x86 and x86_64 Linux installs.
