Thank you. ------------------------------------------------------------------------ [2014-05-21 17:44:29] aharvey@php.net We'll probably need a stack trace with line numbers to be able to diagnose this fully, although it looks like it might be an issue that's getting triggered by PHAR. ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
