Absorb upstream bug fix (their commit e322673a841d9abd69994ae8cd20e191090b6ef4), which prevents a null pointer dereference crash if SN_create_env() gets a malloc failure at just the wrong point. Thanks to Maksim Korotkov for discovering the null-pointer bug and submitting the fix to upstream snowball.
