Compiler bug

[Paul]

Hi,

After attempting to build Haksell programm (through KDevelop),
i have got such a message:


....

Chasing modules from: hask1.hs
Compiling Main ( hask1.hs, hask1.o )
ghc-6.4: panic! (the `impossible' happened, GHC version 6.4):
ds_app_type Main.Tree{tc r16z} [a{tv a1a9}]

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

....


File hask.hs (with little comment) is attached.

Please wright back if you have accepted this signal or 
if you are not interested in such a feedback.

Best regards, Paul.
