Yes it is a bug, but it is a complicated one. FP support is a
historical weakness of gcc. There have never been many of us that cared
enough about FP support to work on it. Thus gcc has poor FP
performance, and some FP bugs like this one. In the 10+ years that this
problem has been known about, no one has ever volunteered to try fix it,
or to pay someone else to fix it. The bug will remain until that
situation changes.
