Miles,

Paul is a maintainer, and so am I :-)

Could you to try again against glibc trunk and see if the issue is
still present?

The community has done a lot of work to fix up libm after the 2.15 release.

If you don't have time to test against glibc trunk please file a bug
in bugzilla and ensure that you mark it with component=math.

Cheers,
Carlos.
