Comment(by diatchki):

 Hello,
 I am sorry that I can't attach the program that causes this behavior---I
 am profiling a large program for work.  I did rebuild everything with
 today's GHC (version 7.3.20111128, git tag
 36f8cabecd5a8320ee174abb56e73841a5cbc9c7) and I am getting the same
 behavior.

 The RTS flags I used: {{{+RTS -K64M -M2G -hb}}}

 Let me know if I can provide some additional information.  The program
 that I am testing has a big memory leak, so maybe another leaky program
 would be able to reproduce the issue?
