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.

Then please consider to accept @laruence's offer (not sure if it's
still valid, though).
