concprog001(threaded2) occasional failures.
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.
