Description:
------------
The symptoms are identical to bug #5895.

The web server silently dies when starting.  Disabling php allows the web server to start, re-enabling php then allows the web server to be restarted once after which it will run correctly.  Any further restarts cause the server to die silently again.  No errors are recorded in the error logs.

PHP Compiled with:
./configure --build=i386-redhat-linux --prefix=/usr --exec-prefix=/usr --bindir=/usr/bin --sbindir=/usr/sbin --sysconfdir=/etc --datadir=/usr/share --includedir=/usr/include --libdir=/usr/lib --libexecdir=/usr/libexec --localstatedir=/var --mandir=/usr/share/man --infodir=/usr/share/info --prefix=/usr --with-config-file-path=/etc --enable-debug --disable-rpath --enable-inline-optimization --with-bz2 --with-exec-dir=/usr/bin --with-freetype-dir=/usr --with-gd --with-gettext --with-gmp --with-iconv --with-jpeg-dir=/usr --with-mm --with-openssl --with-png --with-regex=system --with-ttf --with-expat-dir=/usr --with-zlib --with-layout=GNU --enable-bcmath --enable-ftp --enable-magic-quotes --enable-safe-mode --enable-sockets --enable-sysvsem --enable-sysvshm --enable-track-vars --enable-trans-sid --enable-yp --enable-wddx --without-oci8 --with-imap-ssl --with-kerberos=/usr/kerberos --with-mysql --with-apxs=/usr/sbin/apxs --with-curl


Actual result:

In GDB I get the following error:

Recompiling without -enable-yp had no effect.
