They fix some known memory corruption problems, were merged for > 3.12 (so alternatively just test 3.12) and have been tagged for -stable. I just finished testing with 3.12, and I'm still seeing the same issue. This is actually a bit strange to me, because, when I tested with 3.12-rc5 a while back, everything seemed to be ok (see previoues e-mail in this thread, to Bob Liu). I guess, embarrasingly enough, I must have been playing with a screwed up config that day, and managed to somehow avoid the problem... Either way, it appears that we still have a problem here. I'll poke around a bit more on this in the next few days and see if I can come up with any more information. In the meantime, let me know if you have any other suggestions.
