Sybase is installed stock, 11.9.2, also tried 12.5

./configure --with-mysql=/usr/local/mysql \
--with-apxs=/usr/local/apache/bin/apxs --enable-debug \
--enable-ftp --with-sybase-ct=/opt/sybase-11.9.2

stock php.ini, changed register_globals on, magic_quotes_sybase on, magic_quotes_gpc on

Program that is causing the issue is phpSybaseAdmin 0.0.10 which can be found on freshmeat.

The most common segfaults happen when i click on the master/sysusers table, below is what enable-debug has to say about this:
