Previous Comments: ------------------------------------------------------------------------ [2016-03-31 09:29:22] mbeccati@php.net Description: ------------ I've just re-enabled php7 and master daily builds of phpspec and I am getting an assertion failure. This was the first run in a long time, so I can't tell how recent is the commit that's responsible for the failure on both 7.0 and 7.1. Test script: --------------- git clone git@github.com:phpspec/phpspec.git cd phpspec composer update --prefer-dist php bin/phpspec run Expected result: ---------------- no assertion failure Actual result: -------------- php: /.../Zend/zend_variables.c:43: _zval_dtor_func: Assertion `(arr)->gc.refcount <= 1' failed.
