Bug #65593 [NEW]: Segfault when calling ob_start from output buffering callback.

From: arjen at react dot com Operating system: Linux PHP version: 5.4Git-2013-08-30 (Git) Package: Reproducible crash Bug Type: Bug Bug description:Segfault when calling ob_start from output buffering callback. Description: ------------ Unfortunately no easy to further reduce the testscript. You have to run it using php -e to be able to reproduce it consistently. However, it IS possible to generate without -e. And yes, calling ob_start from output buffer handler is stupid. We found this by accident :-) Test script: --------------- https://gist.github.com/arjenschol/6389030#file-testscript Expected result: ---------------- No segfault, just the fatal error.
