Re: OpenLDAP 2.0.7 problems with binds (ITS#988)
I compiled my version under Solaris 8, with gcc 2.xxx, which I've been told
*might* have a problem regarding memory leaks.
Does anyone know if this is true?
I'm interested to see if anyone has compiled 2.0.7 using cc instead, and
whether it has the same issue.
