Profiling makes FFI Marshalling of Doubles and Int64s fail

[Bayley, Alistair]

(using GHC 6.2.1 under Windows XP)

I'm trying to use the Sqlite (version 3) dll - see http://www.sqlite.org/ .
Marshalling of 32-bit ints and Strings works well, but 64-bit Ints and
Doubles fail (I get garbage back from the FF calls) when I compile with
"-prof -auto-all". If I compile without profiling, everything works as I
expect.

When I try to load the compiled (with -prof) object files in GHCi, it fails
with this error message:

------------------------
Compiling TestCase         ( TestCase.lhs, interpreted )
ghc.exe: panic! (the `impossible' happened, GHC version 6.2.1):
        ByteCodeFFI.mkMarshalCode_wrk(x86) LI_

Please report it as a compiler bug to glasgow-haskell-bugs at haskell.org,
or http://sourceforge.net/projects/ghc/.
------------------------

GHCi works correctly with non-profiled object files.

Thanks,
Alistair.
