#35571 [NEW]: SSI + php (not using virtual()) causes Apache2 segfault
From: kclair at gmail dot com
Operating system: linux
PHP version: 4.4.1
PHP Bug Type: Apache2 related
Bug description: SSI + php (not using virtual()) causes Apache2 segfault
Description:
------------
SSI files which include php scripts are behaving differently after
upgrading from php 4.3.10 to php 4.4.1.
Apache version is 2.0.54.
I tried it with two different configure options:
./configure --with-apxs2=/usr/local/apache2/bin/apxs --enable-debug=no
--enable-versioning --enable-track-vars --with-openssl
--with-jpeg-dir=/home/sys/src/jpeg-6b --with-expat=/usr/lib --with-mcrypt
--with-config-file-path=/home/sys/etc/php-noZend/ --with-png-dir=/usr
--with-zlib-dir=/usr --with-ttf --with-freetype-dir=/usr --with-curl
--with-mysql=/usr --with-gd --with-sablot --with-xslt-sablot --enable-xslt
--disable-zend-memory-manager
./configure --with-apxs2=/usr/local/apache2/bin/apxs --enable-debug=no
--enable-versioning --enable-track-vars --with-openssl
--with-jpeg-dir=/home/sys/src/jpeg-6b --with-expat=/usr/lib --with-mcrypt
--with-config-file-path=/home/sys/etc/ --with-png-dir=/usr
--with-zlib-dir=/usr --with-ttf --with-freetype-dir=/usr --with-curl
--with-mysql=/usr --with-gd --with-sablot --with-xslt-sablot
--enable-xslt
I also tried it both with Zend optimizer enabled and with Zend optimizer
disabled in php.ini.
Reproduce code:
---------------
The includes from the files which segfault look like:
<!--#include file="eventsdb.php?ID=81&fld=2" -->
The php code is a short db query:
if ($conn == false){
echo mysql_errno() . ": " . mysql_error() . "<BR>";
exit;
}
else {
$rtn = mysql_select_db ("[tablename]");
$sql = "select * from events where ID = ".$ID;
$result = mysql_query ($sql);
if ( ($row = mysql_fetch_row($result)) && ($today<=$row[4]
) ){
mysql_fetch_row($result)) {
[snip echo mysql results]
}
}
}
}
Expected result:
----------------
Results from mysql query should be displayed on page.
Actual result:
--------------
Blank pages.
The backtrace is the same regardless of which compile options I used:
