segfault in OS X GHCi when dealing with infinite integers
GHCi happily reports the result of 1/0 to be "Infinity", but negating this value crashes.
GHCi, version 6.10.4: http://www.haskell.org/ghc/ :? for help
Loading package ghc-prim ... linking ... done.
Loading package integer ... linking ... done.
Loading package base ... linking ... done.
Prelude> 1/0
Infinity
Prelude> negate (1/0)
-Segmentation fault: 11
Bug occurs on OS X 10.7.4, ghc installed via MacPorts. This seems to be either an OS-specific issue, or maybe solved in later versions of ghc, since on a linux box it is not reproducible:
GHCi, version 6.12.3: http://www.haskell.org/ghc/ :? for help
