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.

Subject: Re: [PHP-DEV] PHP 7 Segmentation fault
Hi Dmitry,
Yes this is the master branch. I have previously tested it on the
PHP-7.0 branch with the same result. I will do that again to verify
that the
problem is the same.
I run vcsclean, buildconf, configure, make at least once a day. I
do not run the
make install as that will break all the sites on my dev box. I'm
just testing the
new binary with a command line script.
I just did all the steps above and the result is still the same.
I'll try to create a
small script that can be used to reproduce the problem, but it
might be tricky as
it seems to have to do with the number of autoloaded classes, a
problem with
my PHP code (although PHP should not seg fault in that case).
I've just checked for zend_add_live_range - it's even not in the
current master. Also ` grep -rn _live_range Zend/` finds nothing in
PHP-7.0. Could you please check that you're using up-to-date source
tree and the correct branch? It could be pretty much like something
in that direction.
Thanks
