Bug #66575 [Csd]: phpdbg segfaults with Xdebug v2.2.3

Edit report at https://bugs.php.net/bug.php?id=66575&edit=1 ID: 66575 Updated by: krakjoe@php.net Reported by: clicky at erebot dot net Summary: phpdbg segfaults with Xdebug v2.2.3 Status: Closed Type: Bug Package: phpdbg Operating System: Debian 7 (Wheezy) PHP Version: 5.6.0alpha1 Assigned To: krakjoe Block user comment: N Private report: N New Comment: This is fixed and will be included in the next alpha release, or grab a snapshot. From a quick test, xdebug enables output buffering, I had to E ob_end_flush(); to see output. But you should get no errors, and can probably change the behaviour of xdebug with configuration, not really sure ...
