Description:
------------
I ran the script with:
php5 -n -e test.php

I ran it in a loop like this:
for i in `seq 1 100`; do php5 -n -e test.php; if [ $? != 0 ]; then echo; echo Crashed on run $i; echo ; break; fi; done

We don't use MySQL for anything else than pastebin on that machine so we have just moved MySQL off that machine for now, since we primarily uses PgSQL.

The PECL bug reporter doesn't support PHP 5.2.6, so I set it to 5.2.5.

`php5 -n -v` output:
PHP 5.2.6-5 with Suhosin-Patch 0.9.6.2 (cli) (built: Oct  5 2008 12:28:28)

`php -n -i` output, test script, etc.:

I haven't had time to test it on PHP5.3 yet.


Reproduce code:
---------------
<?php
// This script has a seg faults in at
// *least* 1 out of 50 runs. I have a script that
// consistenly fails. But I haven't been able to
// replicate it in a small script.

dl('mysql.so'); // or mysqli.so, but not pdo.so+pdo_mysql.so
dl('fileinfo.so'); // the order doesn't mather

echo "Initializing Fileinfo\n";
$finfo = new FInfo(FILEINFO_MIME);

// If you don't access undefined variables
// it doesn't seg faults.
echo 'foo is'.(isset($foo)?'':' NOT')." set\n";

echo "The script continues...\n"
// High risk of seg fault during shutdown
?>

Expected result:
----------------
Initializing Fileinfo
foo is NOT set
The script continues...

Actual result:
--------------
Initializing Fileinfo
foo is NOT set
The script continues...
Segmentation fault (core dumped)
