--- Comment #8 from Martin Sebor <msebor at gcc dot gnu.org> ---
The plus character should always be followed by a nonempty string.  John, can
you please attach a translation unit to see if by chance I can reproduce with a
cross-compiler?  In parallel, I wonder if there's something funny about
snprintf on HP-UX.  Does the snprintf call added in r12-930 do the right thing
(i.e., append a nonempty string to spec)?
