Both 6.4.2 and HEAD show the problem on OS X. It can be avoided by disabling the threaded rts, but that is not acceptable solution.
This is a good datapoint, because it probably rules out much of the threaded RTS code in the RTS itself, which has changed significantly between 6.4.x and HEAD.
Could you summarize the advantages (or need) of the threaded RTS? It doesn't work under solaris and under linux [1] my nightly compilation jobs are "killed" every tuesday morning (!) for some reason that i cannot reproduce. I suspect the threaded RTS and heavy load. I had no such problems with ghc-6.4.1 before. As a friend of pure functions I hate such a non-deterministic behaviour of a (mere) compiler.
