It worked fine in PHP 4.3.4 and PHP 4.3.5RC2, but PHP 4.3.5 (final) is
broken, and PHP 4.3.6RC3 is broken too. When sybase_free_result is
called, there is segmentation fault (my system is Debian GNU/Linux

Hi there!
The bug ist reproducible here on Debian Woody + apache-1.3.29/php >=

It was most probably introduced while fixing

properly up to php-4.3.4RC2, but not with a patched 4.3.4RC2 to solve
bug #26407 (that patch then made it into 4.3.4RC3).
