This is most definitely a problem with Gosmore.  The fact is, most
roundabouts do not have names, and artificially giving them one to
make a renderer (or routing program) happy is tagging for the
renderer. Even if a roundabout did have a name, I'd be happier if the
routing software just said "turn onto roundabout, take second exit on
Smith Highway" than if it said "turn onto Great Circle, turn onto
Smith Highway". Names on roundabouts are so uncommon that I'd be
looking for a road called Great Circle.

Or are you saying that if the entry and exit roads and roundabout all
have the same name it ignores the roundabout entirely, and this
behaviour is what is broken? That's not too hard a fix to do in a
program. Anything marked as a junction or roundabout should be getting
special treatment anyway. It shouldn't matter if the roundabout has no
name, the name of the street you're on, or the name of a different
crossing street, as long as it is marked as a roundabout.  It's still
a bug if it causes a problem.
