Application gets SegV on AIX with ldap libraries

Hi,
I have an 32bit C application that is running on AIX 5.2-008, and 
intermittently, the program gets a segmentation violation in the ldap 
library layer.

The ldap library that we are using is the 5.08 version.

Here is the stack from the hung process:

Have anyone seen this before?
Is this something that is better handled with a later version of the ldap 
libraries?
