Hello ,

I have similar problem with this code on Apache1.3.22+php4.1.0 linux
2.4.16 RH6.2.  I think this is critical problem.

I configure PHP with:

CC=gcc2.95.3 \
CXX=gcc2.95.3 \
./configure \
--prefix=/usr/local/php \
--with-apxs=/usr/local/httpd/bin/apxs \
--with-config-file-path=/usr/local/php/etc \
--enable-track-vars \
--enable-magic-quotes \
--enable-safe-mode \
--enable-memory-limit \
--enable-sysvshm \
--enable-sysvsem \
--enable-shmop \
--enable-sockets \
--enable-wddx \
--enable-xslt \
--enable-ctype \
--enable-bcmath \
--enable-mailparse \
--enable-ftp \
--with-gd=/export/work/gd-1.8.4-gif \
--with-jpeg-dir=/export/work/jpeg-6b \
--with-png-dir=/export/work/libpng-1.0.9 \
--with-ttf=/export/work/freetype-1.3.1 \
--with-mysql=/usr/local/mysql \
--with-openssl=/usr/local/ssl \
--with-epipe \
--with-mcrypt \
--with-mhash \
--with-zlib \
--with-mm \
--with-xmlrpc \
--with-iconv \
--with-curl \
--with-bz2 \
--with-gmp  \
--with-ldap \
--with-xml  \
--with-zip  \
--with-gettext \
--with-dom \
--with-xslt-sablot \
"$@"
