That's what known as bug-which-is-masked-but-present-otherwhere.

It is exposed in FreeBSD, due to our unusual handling of floating
point errors.  You can hide it by calling fpsetmask() with other
flags; that will make the bug silently create wrong results, instead.

You should report it to the samba team.
