To reproduce the problem, download the attachment and do the following,
 assuming 6.4.2 is the version of the ghc executable in path:

 tar xzf static.tar.gz
 cd static
 make
 ./gens 4                    # works
 ./gens - <tests             # works
 ./gens-prof 4               # hangs


 Several points:

 - ghc 6.4.1 works properly. That's what I'm using for profiling now.
 - At first I thought the problem was with Edison libraries, but an older
 version of the project, without Edison, behaves the same.
 - Removing -auto-all and add -fasm made no difference. I guess that means
 GCC is not at fault.

 By the way, I'm running Gentoo Linux with an Athlon CPU. Let me know if
 you have trouble reproducing the problem.
