        PR fortran/77663
        * caf/single.c (caf_internal_error): Fix not terminating va-list.
        (_gfortran_caf_register): Free memory also when other allocs failed.
        (_gfortran_caf_get_by_ref): Fixed style.
        (send_by_ref): Token is now stored at the correct position preventing
        inaccessible tokens, memory loss and possibly crashes.
