Hi Anatol,
That's odd. I switched back to master and the references to
_live_range() shows up again. I'll try to do a clean checkout and see
what happens. Still on the PHP-7.0 branch with USE_ZEND_alloc=0 set in
the environment I get this backtrace.

Subject: Re: [PHP-DEV] PHP 7 Segmentation fault
Just switched to PHP-7.0 and there is no longer any references to _live_range
but the problem with the segfault is still there. Here is a new backtrace.

Ok, but in master there's no zend_add_live_range() as well, so that is what was
strange. Could you please USE_ZEND_ALLOC=0 to collect the BT?
Thanks
