Please try PHP 4.0.6RC3 from http://www.php.net/~andi/php-4.0.6RC3.tar.gz
and condigure it using also --enable-debug to get 
useful backtrace.

Can you confirm this is still a problem with PHP 4.0.6?

I ended up using the Sybase ct-libraries when compiling PHP and didn't have this problem anymore.

I don't have access to try with a newer version of PHP now.
