@julientld, @ericsten ok, with the backtrace ist's much more clear. I hardly guess this issue
is fixed in the patche within bug #69060.

@julientld please check with any suitable latest snap http://windows.php.net/downloads/snaps/php-5.6/
. Seems this fix didn't land in 5.6.6 yet, but expect it in the 5.6 next.

Thanks.

Here's the registers, call stack (with source lines), and local variables for the first two
stack frames from the crash dump I investigated:
