Does the crash happen in CLI?

I ran apache with gdb to produce this backtrace:
Program received signal SIGSEGV, Segmentation fault.

OK, I've updated the tar ball:
http://jessen.ch/files/php-problem-sep2007.tar.gz
There are now only 5 lines of PHP code. The included file is empty as
is the XSLT stylesheet. I'm pretty certain the problem is actually
caused by the virtual() call, but it doesn't manifest itself till later.

Please cut the script down to minimum code (and without the HTML) that
can reproduce the error. Is this reproduceable running via CLI instead
of within apache? Also a backtrace would be useful as I cant reproduce
this in Linux or Windows.

Description:
Loading an XSLT stylesheet with a syntactical problem causes Apache to
segfault. Looks like bad error-handling.
Reproduce code:
---
http://jessen.ch/files/php-problem-sep2007.tar.gz
Let me know if you need a core dump or anything else. The above will
produce a segfault every time problem.phtml.en is loaded.
Expected result:
Apache segfault.
