If the exact same input produces different results depending on whether
or not you add and endl before the function call would probably count as
a bug. Could be something like a status bit that does not get cleared
when it should be.

However, since this is such a gcc specific issue I would suggest you
take this upstream: http://gcc.gnu.org/lists.html . People there will
probably be able to help you better than the people on this list.
