Bug description: Some memleaks from valgrind
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:
