Summary: Problem with where clause and Template Haskell

Initial Comment:
When compiling the two files attached, the following
happens:


$ ./compile.sh 
Chasing modules from: TemplateTryOut.hs
Skipping  Templates        ( ./Templates.hs,
./Templates.o )
Compiling Main             ( TemplateTryOut.hs,
TemplateTryOut.o )
Loading package base ... linking ... done.
Loading package haskell98 ... linking ... done.
Loading package haskell-src ... linking ... done.
compiling template
ghc-6.2.1: panic! (the `impossible' happened, GHC
version 6.2.1):
        nameModule readTread_d1z7

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


I think it's a problem with template haskell. The first
call of 'template' in TemplateTryOut.hs (line 10)
succeeds, as you can see from the message 'compiling
template'. The second call in line 17 fails. The only
difference between these 2 calls is the where clause.

This bug is fixed in the HEAD and in the up-coming 6.2.2

Do test it again when you get 6.2.2!
