AW: Heap profiling in GHC broken?

[Markus.Schnell at infineon.com]

I have no idea how to set up cvs under windows to get things 
from a non-local repository, but anyway, profiling worked on 
the macintosh.

I spent the whole weekend plus monday to find the space leak,
but eventually I did. 
Heap Profiling was very helpful there.

Unfortunately, space leaks are barely mentioned in the Haskell
books/tutorials, but they are a real burden if you want to run 
programs for larger problems.

A tutorial on this by one of the experts would be very welcome.
:-)

Thanks,
Markus
