Seems to be always for the same cause for me.

Both stacktraces show up a call to _zval_dtor_func which ultimately get a segfault in the garbage collector. That is an exact duplicate of bug 43972 which was open against the continuous integration server. See https://bugzilla.wikimedia.org/show_bug.cgi?id=43972#c11 for a workaround. PHP bug is https://bugs.php.net/bug.php?id=63055 *** This bug has been marked as a duplicate of bug 43972 ***
Thanks for the info, Antoine.
