Hi Simon, I followed the instruction in DebuggingGhcCrashes, and the instructions in the ghc commentary for building an rts with debugging and symbols. (Please let me know if there are any mistakes in these instructions that you know of!) The crash seems to always happen eventually, but I do not have a simple case that reproduces it quickly. Gdb's traceback doesn't give anything immediately useful, so I assume that the crash is in haskell code, not in C. The not-always-reproducible nature of the bug suggests deferencing a pointer into uninitialized memory. 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. If I am to take a few deep breaths and dive back into the problem, which branch should I use, 6.4.x or HEAD?

Thanks, now comitted and merged.
I've banged my head on ticket #751, building with debugging symbols and running under gdb, but have yet to get any useful information that would pin down the bug.
Does http://hackage.haskell.org/trac/ghc/wiki/DebuggingGhcCrashes help at all?
