I can think of an implementation that would track the length trimmed to and conserve the memory. My point being that this level of behavior, using temporaries or not, IMNSHO, is implementation detail that does not belong in the standard if it is there. c.l.f folks sometimes get a bit esoteric in their discussions. I am closing this bug as not a bug (invalid). I do appreciate the report though. We do not want to miss things and its better to error on the safe side and report then not. -- jvdelisle at gcc dot gnu dot org changed: What|Removed |Added Status|UNCONFIRMED |RESOLVED Resolution||INVALID http://gcc.gnu.org/bugzilla/show_bug.cgi?id=45463

Update: More responses in comp.lang.fortran bring up the point that if trim(line) is supposed to return a temporary, the code might be conforming.

When I looked after I had posted the question there was only one response and that response said it was a bug so I submitted this bug report.
