Comment:
I wasn't able to reproduce this on OpenBSD/amd64 with ghc 6.8.2.
The program runs to completion:
{{{
$ ./A +RTS -N2
500000
}}}
On a 4 core linux box, however, I triggered some faults:
{{{
$ ./A +RTS -N2
500000
$ ./A +RTS -N2
A: internal error: evacuate: strange closure type 23552
(GHC version 6.8.1.20071114 for i386_unknown_linux)
Please report this as a GHC bug:
http://www.haskell.org/ghc/reportabug
$ ./A +RTS -N4
zsh: segmentation fault ./A +RTS -N4
}}}
