Description:
------------
It seems that compiling this into PHP statically with --enable-maintainer-zts and --enable-runkit so it uses the sandbox causes PHP to crash no matter what command/script you run. Also, when this is compiled as a shared object it returns an error about: undefined symbol: compiler_globals

If there's anything else useful you need, let me know.

Reproduce code:
---------------
php -v

Expected result:
----------------

Please try a snapshot.  I havn't managed to reproduce the shared object problem, but the crash in the static build is (probably) fixed as a result of the recent refactor of runkit_sandbox.c

Erm.... by snapshot I mean just grab the up to date CVS... PECL != Core :p

Works from CVS. I can't reproduce the shared object problem either. I think it was just because I was loading the wrong one, but it works now either way. Thanks.
