hi,
during the last month or so, the threads test in 1.9.x has been failing
for me (debian unstable, x86 box) intermittently, with the message:
FAIL: threads.test: lock-mutex: timed locking succeeds if mutex unlocked
within timeout
it happens every now and then, but i haven't been able to pin down the
cause (i'm not familiar with the code and haven't looked at it much), or
to reproduce the error consistently (although with the current it seems
to happen almost always). am i the only one?
cheers,
jao

No, I think I've seen this too. Intermittently though, as you say.

I get the same fairly often when I compile CFLAGS="-g3 -gdwarf-2 -O0".
I imagine that it is the "-O0" zero optimization that has something to
do with it.
