Negative doubles or floats in Haskell (macports)

Question

Why do I get a segmentation fault when I try to show a negative double or float? There is no problem for negative integers.

Prelude> let a = 4
Prelude>         


        

Answer 1

March 2011: This is fixed in the GHC 7 release of the Haskell Platform, where both 32 bit and 64 bit Mac native ports are in fine condition.
