From: [EMAIL PROTECTED]
Operating system: Linux 2.4.3-12 (Apache/1.3.20)
PHP version: 4.1.0
PHP Bug Type: XSLT related
Bug description: segmentation fault
[Note: PHP version is 4.1.1 -- the drop-down box has 4.1.0 as latest
version]
Script:
<?
$processor = xslt_create();
$args = array();
$args[ '/xml' ] = '<?xml version="1.0"?><root />';
$args[ '/xsl' ] = '<?xml version="1.0"?><root />';
for( $i = 0; $i < 1000; ++$i )
{
if( !$result = xslt_process( $processor, 'arg:/xml', 'arg:/xsl',
NULL, $args ) )
{
echo 'failed';
}
}
xslt_free( $processor );
echo 'done';
?>
Config line:
'./configure' '--with-config-file-path=/etc' '--with-pgsql'
'--with-apxs=/usr/apache/bin/apxs' '--with-xml' '--enable-xslt'
'--with-xslt-sablot' '--with-mysql=no' '--with-gd' '--enable-debug'
Description:
When I visit this script, and hit refresh (several times) Apache terminates
with a segmentation fault. The bug appears to be random because there are
times when the script finishes without a crash.
