CVS HEAD ghc fails with "Panic!"

[Simon Peyton-Jones]

I reckon I've fixed this, at last.

| Hi,
| 
| the GHC version from the current CVS HEAD aborts with an
| internal error when doing this:
| 
|  $ darcs get http://cryp.to/hsemail
|  $ cd hsemail
|  $ ghc -O2 --make -o message-test message-test.hs
|  | Chasing modules from: message-test.hs
|  | Compiling Rfc2234          ( ./Rfc2234.hs, ./Rfc2234.o )
|  | ghc-6.3: panic! (the `impossible' happened, GHC version 6.3):
|  |         app_match: unbound tpl c{tv a1a9}
| 
| Compiling with -O instead of -O2 works, though.
| 
| Peter
