Seems to be related to
http://lists.php.net/article.php?group=php.internals&article=8103 (which
was fixed for most cases I was able to reproduce it with).
Here, too, I do not have a nice short script (I've started migrating a
rather largish framework to PHP5) but from a quick glance it only shows
up in case a fatal error has been issued (in this case: Call to a member
function open() on a non-object, in another: Call to undefined function
com_release()).
Program received signal SIGSEGV, Segmentation fault.
