When compiling the two files attached, the following

$ ./ 
Chasing modules from: TemplateTryOut.hs
Skipping  Templates        ( ./Templates.hs,
./Templates.o )
Compiling Main             ( TemplateTryOut.hs,
TemplateTryOut.o )
Loading package base ... 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,

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.
