Thanks. --------------------------------------------------------------------------- [2000-12-21 10:37:55] kalowsky@php.net I spent some time this morning looking into this bug and have been unable to reproduce it. I was able to crash the Netscape browser multiple times over though...take that for what you will. I am also unable to access your 8080 sample page unfortunately. uname -a FreeBSD CatchallServer.tics35.eng.tvol.net 4.2-STABLE FreeBSD 4.2-STABLE #5: Tue Nov 21 08:22:09 EST 2000 root@CatchallServer.tics35.eng.tvol.net:/usr/src/sys/compile/SERVER i386 CatchallServer# pkg_info | grep gd gd-1.8.3 A graphics library for fast PNG creation CatchallServer# pkg_info | grep apache apache+mod_ssl-1.3.14+2.7.1_1 The Apache 1.3 webserver with SSL/TLS functionality apache-1.3.14 The extremely popular Apache http server. Very fast, very c I do not use mysql nor do I use the pcre-regex config lines. Excerpt from local phpinfo: System FreeBSD intern6.eng.tvol.net 4.2-RELEASE FreeBSD 4.2-RELEASE #25: Tue Nov 21 08:29:37 EST 2000 Build Date Dec 11 2000 Configure Command './configure' '--with-imap' '--with-pgsql' '--with-gettext' '--enable-snmp''--enable-track-vars' '--enable-wddx' '--with-gd=/usr/local' '--enable-trans-sid' '--disable-magic-quotes' '--enable-short-tags' '--without-mysql' '--with-apxs=/usr/local/sbin/apxs' '--without-tsrm-pthreads' '--prefix=/suproot/usr/local' I'm currently bringing down a more recent version of PHP to try this with again. This has also been tested on a machine build with the same config file under XFree864.0.2, for which PHP seems to require some of the truetype fonts when built with gd (??). Again, the provided sample file cannot seem to crash the apache server. Again the machine is a FreeBSD 4.2-STABLE system. --------------------------------------------------------------------------- [2000-12-13 13:21:15] goten@mylaptop.com [root{509}]# gdb /usr/local/apache1/bin/httpd GNU gdb 4.18 Copyright 1998 Free Software Foundation, Inc.
