Description:
------------
When runnig my C application using PHP SAPI, valgrind reports some mem leaks that appear to be coming from ZEND/SAPI.

Reproduce code:
---------------
The line that is pointed to by valgrind is:

php_embed_init(argv, argc PTSRMLS_CC);

The entire php.c can be seen at http://crispycrisp.org/php.txt

Expected result:
----------------
No me leaks

Actual result:
--------------
Here is the entire valgrind output:
http://crispycrisp.org/valgrind.txt

Those leaks are quite obviously outside PHP code.

Yes and they are quite obviously outside my C code. As I'm using the PHP SAPI doesn't that make it relating to php.net?
