Description:
------------
Compilation with PHP 5.1.x fails..

i tried to fix it in ffi.h from libffi with :

#elif SIZEOF_LONG_LONG == 8
 #ifdef PHP_WIN32
 # define UINT64  LONG64
 # define SINT64  INT64
 #elif
 # define UINT64  unsigned long long
 # define SINT64  long long
 #endif
#endif

compilation works but php crashes when we call a ffi object method

the fatal error is in ffi_library.c, in php_ffi_call_method function :

Fixed with try catch at Line 508 :

	zend_try {
		if (args) {
			efree(args);
		}
	
		for (i = 0; i < nargs; i++) {
			if (need_free[i]) {
				efree(values[i]);
			}
		}
	
		if (values) {
			efree(values);
		}
	
		if (return_value_buf) {
			efree(return_value_buf);
		}
	
		if (need_free) {
			efree(need_free);
		}
	}
	zend_catch {} 
	zend_end_try();
