Bug #73667 [NEW]: Segfault when using phpunit with large test suites
From: ilya at antipenko dot pp dot ua
Operating system: Ubuntu 14.04.5/12.04
PHP version: 7.0.13
Package: Reflection related
Bug Type: Bug
Bug description:Segfault when using phpunit with large test suites
Description:
------------
Hello.
I'm getting this segfault on travis-ci (php 7.0.13) when I run unit
tests (phpunit 4.8/5.2).
Unfortunately, it's a private repo and I can't reproduce this segfault
with synthetic test.
Also, this segfault disappears after using additional phpunit options
(like --testdox)
Also, we are using
https://github.com/mybuilder/phpunit-accelerator/blob/master/src/TestListener.php#L46
to cleanup test after it finished. Probably, it can cause lots of
reflection usages which causes memory corruption.
I know, there is a bit of information, but I hope we can found and fix
it together.
