Operating system: Fedora Core 3 (FC3)
PHP version: 5.1.2
PHP Bug Type: MySQL related
Bug description: *** glibc detected *** double free or corruption
Description:
------------
After an upgrade of MySQL from 3.23 to 4.0, I kept getting "mysql_connect
not a valid function call". So I recompiled php.
Then I got a blank scrren on the browser. When run, "~php ./test.php"
produces an error message (which can't be seen in the browser). The
solution for me was to "export MALLOC_CHECK=0;" on the command line, so
glibc stops going crazy then restart httpd. I set this env variable in my
.bash_profile. It seems to work fine so far.
Reproduce code:
---------------
<?php
error_reporting(E_ALL);
$link = mysql_connect('localhost', 'user', 'password');
if (!$link) {
die('Could not connect: ' . mysql_error());
}
echo 'Connected successfully';
mysql_close($link);
?>
Expected result:
----------------
Connected successfully
Actual result:
--------------
*** glibc detected *** double free or corruption
