VMS Help CC, Messages, NORETNONVOID  *Conan The Librarian (sorry for the slow response - running on an old VAX)

 Message        noreturn assertion of #pragma assert directive can't
                be specified for non-void function.

 Description    noreturn assertion was specified in #pragma assert
                directive for non-void function; the noreturn
                assertion will be ignored.

 User Action    Either remove noreturn assertion from the directive,
                or change return type for the function to void.
