After switching to persistant OCI connections the error seems to be
gone?!?!?!?!?!

Description:
------------
When running a PHP Skript with Oracle calls then very often the apache
process dies and produces a SIGSEV error.
My configuration is:
./configure
--with-apache=../apache_1.3.27
--with-xml
--enable-wddx
--with-ldap=/usr/local
--with-openssl=/usr/local/ssl
--with-curl=/usr/local
--with-zlib
--with-oci8=/opt/oracle/ora920
--without-mysql
--with-config-file-path=/etc/apache
--enable-debug
--prefix=/usr/local
The first occurrence of the error has the following backtrace:
Program received signal SIGSEGV, Segmentation fault.
