I link postfix against OpenLDAP libraries for its ldap lookups.  With my
previous CVS checkout of RE24 (12/9/2008) there were no problems with this. 
However, I updated to CVS of RE24 as of 1/30/2009, and now the postfix proxymap
binary always segfaults:

Core was generated by `proxymap -t unix -u'.
Program terminated with signal 11, Segmentation fault.

This is likely related to the recent TLS changes in RE24.
