Not sure whether I experience the same bug or not, but here is bt in travis build:

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

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 -

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: 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 Will provide report there.
