Description

I got a ghc "panic" when trying to compile some code
which made use of .hi-boot files.  The exact panic
message was

ghc-6.0.1: panic! (the `impossible' happened, GHC
version 6.0.1):
        typecheck/TcRnTypes.lhs:233: Missing field in
record construction TcRnTypes.top_errs

This was on a RedHat 8.0 Linux system,
with the following version of ghc:
Glasgow Haskell Compiler, Version 6.0.1, for Haskell
98, compiled by GHC version 6.0

I apologize for the incompleteness of this bug report,
but unfortunately the source code which triggered this
bug is proprietary, so I can't include it here.  Sorry!

Put the summary back.  Not sure what happened there.
