Re: OpenLDAP 2.0.7 problems with binds (ITS#988)

[donnelly@sendmail.com]

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.
