Operating system: GNU/Linux 2.4.18-19.7.x (RedHat)

PHP Bug Type: Reproducible crash
Bug description: References to object members seem to be backwards
ereg(..., null) is causing a crash in Apache, but not in command line mode.
I'm using the following file in /path/to/htdocs/test.php:
<?php
define_syslog_variables();
openlog('ereg() test', LOG_CONS | LOG_PERROR, LOG_USER);
header("Content-Type: text/plain\r\n");
syslog(LOG_ERR, "one\n");
echo "one\n";
ereg('wsdl', $unsetVariable);
syslog(LOG_ERR, "two\n");
echo "two\n";
?>
Nothing fancy, just trying to call ereg() with an unset variable as a
second argument (the nusoap package at http://dietrich.ganx4.com/nusoap/
does this all over the place). This used to work just fine with 4.2.3.
If I run it from the 4.3.0 command line, it works as well:
$ php test.php
ereg() test: one
X-Powered-By: PHP/4.1.2
Content-Type: text/plain
one
ereg() test: two
two
However, if I go to that page in a web browser, I get nothing back and
this in the logs:
ereg() test: one
FATAL: emalloc(): Unable to allocate 1449143544 bytes
ereg() test: one

ereg() test: one

ereg() test: one
FATAL: emalloc(): Unable to allocate 1449143544 bytes
ereg() test: one
FATAL: emalloc(): Unable to allocate 1449143544 bytes
The weird thing is that if I call ereg('', ''); once in the program before
all other ereg() calls, everything works as before (shared state
initialization? are these thread safe?).
I'm using apache_1.3.27, curl-7.10.2, libxml2-2.4.30, libxslt-1.0.23,
mod_ssl-2.8.11-1.3.27, openssl-engine-0.9.6g, and php-4.3.0 (everything
else comes from the most up-to-date RedHat 7.3 distro).
Here is my Apache 1.3.27 build configuration (pretty simple). I'm using
