Hi,
I think this bug is serious and should be turned into a ticket on
http://hackage.haskell.org/trac/ghc/
Would you do so Sönke?
The abstraction of floats (Float or Double) is broken if equality
considers (random and invisible) excess bits that are not part of the
ordinary sign, exponent an

All,
I sent this mail to Haskell Cafe earlier today, and was pointed [1] at

It looks like you're making a ForeignPtr from the Addr# or Ptr that
points to the contents of the ByteAr

You have to be 100% consistent in how you do every operations in all cases
otherwise dif

Hello,
I am late to the discussion and this is not entirely on topic, for which I
apologize, but I like the multi-branch case syntax someone mentioned
earlier:
Writing:

> | ...
desugars to:
> case () of
> _ | p1 -> e2
> | p2 -> e2

ghc-7.4.2 should also build fine on Fedora 17 ARM.
Just "yum install ghc llvm" first.
I can provide a src rpm if it helps.
