Bug Type: Reproducible crash
Operating System: Linux Redhat 8.0
PHP Version: 4.2.2
New Comment:
Did you do make clean & removed config.cache before compiling PHP with
--enable-debug flag?
Also, try running the php via gdb,
gdb /home/rsaura/php-4.3.0/sapi/cgi/php
run -f pp.php4
If your php binary does have debug symbols and the backtrace is still
uninformative it is likely the crash is occuring within the ldap
library itself.

I've configured PHP-4.3.0 this way:
./configure --host=i686-pc-linux-gnu --build=i686-pc-linux-gnu
--target=i386-redhat-linux-gnu --program-prefix= --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
--sharedstatedir=/usr/com --mandir=/usr/share/man
--infodir=/usr/share/info --prefix=/usr --with-config-file-path=/etc
--enable-force-cgi-redirect --enable-debug --enable-pic --disable-rpath
--enable-inline-optimization --with-dom=/usr --with-exec-dir=/usr/bin
--with-gettext --with-regex=system --with-xml --with-expat-dir=/usr
--with-zlib --with-layout=GNU --enable-exif --enable-ftp
--enable-magic-quotes --enable-safe-mode --enable-sockets

--enable-track-vars --enable-trans-sid --with-pear=/usr/share/pear
--with-ldap --enable-memory-limit --enable-shmop --enable-versioning
but the new core file does not show any debug symbol:

Could you compile your PHP with --enable-debug flag, so that your
backtrace contains more information.

This bug has been fixed in CVS.
In case this was a PHP problem, snapshots of the sources are packaged
every three hours; this change will be in the next snapshot. You can
grab the snapshot at http://snaps.php.net/.
In case this was a documentation problem, the fix will show up soon at
http://www.php.net/manual/.
In case this was a PHP.net website problem, the change will show
up on the PHP.net site and on the mirror sites in short time.
Thank you for the report, and for helping us make PHP better.
The 4.3.0 release will soon be released as 'stable', the RC4 is
probably 99.5% of what the 4.3.0 final will be. If using 4.3.0 solves
the bug, that is the release you should probably use.

It works with php4-200212231630.
Does anybody know if this is patched on a production release?
