Concurrency problems on Mac OS X?

[Jeff Leung <jeffleung@mac.com>]

Hi,

I am trying to get OpenLDAP 2.1.3 over BerkeleyDB 4.0 running on Mac OS X
(10.1.5) and am running into problems with test008-concurrency. Basically, I
get what I guess is the Darwin equivalent of a core dump (internal error?).
My output for test008 looks like:

>>>>> Starting test008-concurrency ...

Looking in the bug list archives, I see that this might have been discussed
as a problem with how pthreads was implemented in Darwin, but this was a
full year ago; I imagine that the problem discussed back then would be fixed
by now.

Is there a workaround for this, or is this perhaps a different problem? I
can provide a back trace if it will help.

Thanks.
