I've stumbled into the same problem a few weeks ago, I even reported it
to this list. It took me quite a while to figure out what happened.

I'd consider this to be at least half a bug.
I'm an OpenBSD guy, but we're probably using very similar versions
of gas. This email is Cc:ed to egcs-bugs, as this ties two bug-reports
together, but could you please contact me privately---I'm very interested
in comparing notes, and possibly getting together a patch to gas that
would solve this specific problem.
