Comment (by guest):

 Reproduced it on a dual Opteron running Fedora 8:

 [breitko at megadodo haskell]$ ./parallel +RTS -N2
 500000
 [breitko at megadodo haskell]$ ./parallel +RTS -N2
 parallel: internal error: evacuate: strange closure type -3932344
     (GHC version 6.8.2 for x86_64_unknown_linux)
     Please report this as a GHC bug:
 http://www.haskell.org/ghc/reportabug
 Aborted
 [breitko at megadodo haskell]$ ./parallel +RTS -N2
 Segmentation fault
 [breitko at megadodo haskell]$ ./parallel +RTS -N2
 500000

 Successful run, internal error, and segfault seem about equally likely.
