Not sure whether I experience the same bug or not, but here is bt in travis build: https://travis-ci.org/pinepain/php-weak-lib/builds/101496046#L443

Happened when I try to run tests against PHP nightly build with my php-weak extension.

With php 7.0.0 build is green with and without codecoverage https://travis-ci.org/pinepain/php-weak-lib/builds/101491413.

Worth to mention that my ext backup obj handlers and then replace it with modified handler struct where dtor_obj wrapped with custom ext function.

Here is valgrind report - https://gist.github.com/pinepain/aae4eff78695b8808a48

Could you please try Xdebug from github's master branch? I fixed a few things. If that doesn't fix it, I will need to have short script that reproduces the issue please. To go with that, a nice backtrace (hints on how to make them: https://bugs.php.net/bugs-generating-backtrace.php) would be great too.

I tried on my local machine, php is from master and xdebug too. Same result. After digging yesterday around a bit and disabling all extension it looks like my report should goes to http://bugs.xdebug.org/view.php?id=1246. Will provide report there.

I am closing this, as joefallon never replied with additional information, and http://bugs.xdebug.org/view.php?id=1246 is confirmed fixed by zaq178miami.
