PHP 4.0 Bug #4558: segfault on client request (linux & mod_php )

Hello, I have a problem with php release 4.0.0 in that it segfaults whenever a client connection is made. All components below are clean built with gcc. The details of my configuration are below - I am not sure if its exactly the same as BUG 4558 but it looks like it. How can I debug the backtrace below further?? Has anyone come across this as well - or is it just me doing a dodgy installation?? many thanks, Roger Foskett -------- VERSIONS INFO -------- Linux 2.2.14-15mdk (mandrake) Apache 1.3.12 (built as APXS - works fine with mod_perl) php 4.0.0 (built as APXS) Related bug: 4558 (http://bugs.php.net/bugs.php?id=4558) -------- Error log message -------- [Mon May 22 22:09:16 2000] [notice] child pid 2101 exit signal Segmentation fault (11) -------- PHP CONFIG -------- ./configure \ --with-apxs=/usr/local/apache/bin/apxs \ --with-config-file-path=/www/conf \ --with-gd \ --with-mysql (gd, zlib & mysql all installed ok) -------- PHP INI -------- standard php.ini (php.ini-dist) in /www/conf/ -------- APACHE CONFIG -------- (largefile support required to stop mod_perl-1.23 segfaults - as perl is largefile enabled) CFLAGS="-D_LARGEFILE_SOURCE -D_FILE_OFFSET_BITS=64" \ ./configure \ --sysconfdir=/www/conf \ --logfiledir=/www/logs \ --enable-module=most \ --enable-shared=max \ --enable-module=rewrite \ --enable-shared=rewrite -------- BACKTRACE -------- (the seg fault was caused by telnetting into port 80 and typing GET - couldnt produce a core file) [root@mako bin]# gdb ./httpd GNU gdb 19991116 Copyright 1998 Free Software Foundation, Inc.
