Solaris 9, Sun Studio 12, fully patched. I don't optimize OpenLDAP. 
CFLAGS="-g -xs -KPIC -xarch=v9". It's the same hardware I've been using 
for OpenLDAP testing for years. (Obviously compilers/patch levels/etc. 
change over time, but still...). And I have had other segv's with this 
checkout, e.g. earlier:

2.3.39 tested clean on the same box on Nov 8, 2.3.38 worked on Oct 5, 
2.3.37 worked on Jul 30, RE24 (prior to 2.4.6) worked on October 23, 
etc...

I was thinking about this -- watchmalloc dying in a mutex unlock. Is there 
a chance that it's unlocking something it doesn't really hold? I vaguely 
remember this being a "feature" of Sun's implementation, but it's been a 
while...

Fair enough. I'll try stressing test008.
