Description:
------------
I was running a preg_split to split a string by ";" (taking care not to split
enclosed ";" of SQL sentence) results a preg_split crash without notice and error.
The test script is only 3 lines.
I'm using PHP 5.3.6, cannot upgrade because the hosting is stuck at this version.
Test script:
