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.

Program received signal SIGABRT, Aborted.

Can you please provide the backtrace for this assertion failure? That would be "bt" in gdb.
