Re: 1.12.5 pserver core dump pid-11993

I have tested this. It is repeatable on solaris 2.8. I setup two
workareas from the same repo/module and commited at the same time,
one proceeded one got the waiting on lock. Once the one waiting on
lock gets the lock, it core dumps.

Please take a look at this. Our integration with another tool
fails and the integration process is left in a uncertain state of
reliability.

cvs 1.12.5 non-root pserver, solaris 2.8, compiled with workshop
6.1, MMAP commented out in config.h

Thanks,

Mark
