Comment(by ndaniels):

 I have attached source code for my program that will exhibit the crash.

 If you trigger the call to "error" on Beta.hs line 55, you should get the
 runtime system crash if you're running with enough threads.

 Try this:

  ./mrfy --gens 1000 --converge 50 --multipop 10 testing/sandwich.hmm+
 testing/sandwich.fasta +RTS -N8

 You should be able to compile it via mk or cabal, or simply `ghc --make
 Main.hs -O2 -o mrfy`. I will note that there are a number of dependencies,
 which the cabal file should resolve.
