RE: GHC-6.4.1 much slower than GHC-6.4

Excellent, thank you.  We'll commit a fix shortly.   The bug isn't in
the HEAD, but it's certainly in 6.4.1

| 
| The file
| 
| http://liinwww.ira.uka.de/~rahn/bugCW/Body.hs
| 
| contains a small(er) piece of code that shows the behavior as well.
| Just run make from
| 
| http://liinwww.ira.uka.de/~rahn/bugCW/Makefile
| 
| to get the *.prof files in
| 
| http://liinwww.ira.uka.de/~rahn/bugCW/
| 
| With ghc-6.4 is unimportant whether we use 'where' or 'case' syntax.
In
| ghc-6.4.1 the 'where' syntax repeats some computation.
| 
| Hope it helps, regards, Mirko Rahn
