TH quasi-quoting bug - fails on quoting where clause in let declcontext

[Simon Peyton-Jones]

How true.  Thanks for reporting this.  It's fixed in the HEAD.

	Could merge to STABLE branch if we do another 6.2 release
	(but I doubt we will)

sorry about the delay on this one

Simon

declcontext
| 
| 
| In ghc 6.2 and 6.3 (CVS as of early March) evaluating the following in
| ghci gives an "impossible happened" error.
| 
| do {d <- runQ $ [| let foo = bar where bar = 3 in foo |];  print d}
| 
| The bit that causes the problem is the where in the declaration
context
| introduced by the let.
| 
| ghci-6.2 says:
| 
| ghc-6.2: panic! (the `impossible' happened, GHC version 6.2):
| 	nameModule bar_d1yu
| 
| and ghci-6.3 says something similar
| 
| ghc-6.3: panic! (the `impossible' happened, GHC version 6.3):
| 	nameModule bar{v} {- v aFI -}
