Apache 1.3.17 dumps core on startup if I try to load the php module dynamically.

These are my dynamic loading settings:

LoadModule agent_log_module   libexec/mod_log_agent.so
LoadModule referer_log_module libexec/mod_log_referer.so
LoadModule info_module        libexec/mod_info.so
LoadModule rewrite_module     libexec/mod_rewrite.so
LoadModule expires_module     libexec/mod_expires.so
LoadModule php4_module        libexec/libphp4.so

What is really strange is that if I disable mod_log_agent and mod_log_referer, it works fine!


I configured PHP with:

./configure --with-apxs=/usr/local/apache/bin/apxs --enable-ftp --without-mysql --with-oci8=/home/oracle/u01/app/oracle/product/8.1.7 --with-pgsql=/usr/lib

and then with --enable-debug to get the following backtrace:
