Operating system: linux/macos
PHP version: 7.1.7
Package: Reproducible crash
Bug Type: Bug
Bug description:Segmentation fault in zend_mm_alloc_small
Description:
------------
This crash happens in exactly the same place each time i run this
script. Its actually my entire phpunit suite for a big project, so its
not easy to pin down a short reproducible test script.
If I run the individual test where the crash happens only there is no
crash.
I have tried running, calling gc_disable() at the start and this crash
doesnt happen.
Its a Symfony project, and the crash only happens with Symfony 3.3, no
crashes for Symfony 3.2, but the size of a Symfony update makes it hard
to put a finger on the change that causes the issue.
Only crashes on php >7.1 - its fine on <=7.0.
I'm very willing to provide more information, I just dont know what to
add at this point.
Actual result:
--------------
Core was generated by `php ./vendor/bin/phpunit'.
Program terminated with signal SIGSEGV, Segmentation fault.
