I'm trying to run PHP in my own multithreaded environment.
Memory leaks are critical for my application.

I've tried to track the leaks down using memprof and I think
I've found a leak in basic globals destructor:                      

There's original basic globals destructor source 
from PHP 4.2.1:                            

static void basic_globals_dtor(php_basic_globals *basic_globals_p TSRMLS_DC)
{
 	zend_hash_destroy(&BG(sm_protected_env_vars));
	if (BG(sm_allowed_env_vars)) {
		free(BG(sm_allowed_env_vars));
	}
#ifdef PHP_WIN32
	CoUninitialize();
#endif
}

There's an item called url_adapt_state_ex in the BG array which seems to
be no deallocated in the destructor. 

I've tried following modification:

static void basic_globals_dtor(php_basic_globals *basic_globals_p TSRMLS_DC)
{
 	zend_hash_destroy(&BG(sm_protected_env_vars));
	if (BG(sm_allowed_env_vars)) {
		free(BG(sm_allowed_env_vars));
	}

        if (BG(url_adapt_state_ex).tags)
	{
       	 zend_hash_destroy(BG(url_adapt_state_ex).tags);
         free(BG(url_adapt_state_ex).tags);
	}

#ifdef PHP_WIN32
	CoUninitialize();
#endif
}
 
I don't know if my modification is clean, but it seems to solve the problem.
