Comment(by simonmar):
We lack a way to reproduce the problem here, so it is hard for us to track
it down. There are basically three ways to track this down:
* Compile GHC with profiling and `-fprof-auto`, and run it with `+RTS
-xc` to get a stack trace. You will probably need to hit Control-C to
interrupt the hanging GHC, the RTS should then spit out the stack trace.
* Insert lots of `trace`s in the compiler to try to find out where it has
hung.
* Use gdb and poke around in the stack of the blocked thread to try to
find out where it is stuck. See [wiki:Debugging/CompiledCode].
