What is the bug report in Bugzilla for this issue, which presumably is
user-visible in a release so should have a bug report? If there isn't
one, please file one; in any case, include the [BZ #N] annotation in the
ChangeLog entry (and a commit of a fix should include updating NEWS).
(If the issue isn't user-visible in a release and so doesn't need a bug
report, please explain why not. But any bug being fixed that was
user-visible in a release should have a corresponding Bugzilla entry.)
In my view you should add a testcase for this issue for log to
libm-test.inc, even if there are tests for other functions that show the
problem as well.
