PHP Bug Type: Reproducible crash
Bug description: Segmentation fault in httpd child process when using user
authentication
I am using Apache 1.3.22 and PHP 4.1.0 on RedHat Linux 7.0.
When I view the following script, or any similar scripts with user
authentication features, the page comes up as "can't be displayed", a look
in the error_log shows the error "child pid 25693 exit signal Segmentation
fault (11)" (obviously a different pid each time).
The script is:
<?php
if(!isset($PHP_AUTH_USER)) {
header("WWW-Authenticate: Basic realm=\"My Realm\"");
header("HTTP/1.0 401 Unauthorized");
echo "Text to send if user hits Cancel button\n";
exit;
} else {
echo "<p>Hello $PHP_AUTH_USER.</p>";
echo "<p>You entered $PHP_AUTH_PW as your password.</p>";
}
?>
My PHP configure line was:
./configure --prefix=/opt/server/php --with-mysql=/opt/server/mysql
--enable-ftp --enable-safe-mode --enable-track-vars
--with-apache=../apache_1.3.22
My Apache configure line was:
./configure --prefix=/opt/server/httpd
--activate-module=src/modules/php4/libphp4.a
--activate-module=src/modules/perl/libperl.a
