Description

This one has so far resisted my attempts to debug it. The most common error is "thread blocked indefinitely": I don't know whether it's a bug in the RTS or allowed behaviour for this program, but it only seems to occur on a multiprocessor with +RTS -N2, and only in one out of 10 runs or so.

Also I've seen

  • hanging using 100% CPU without apparently making any progress
  • another type of crash I didn't make a note of at the time.

We've had no more concprog002 failures since the recent round of throwTo fixes (#2910), so I'm optimistically assuming this is fixed.
