I don't get this by default, but can force it by compiling with no-ec2m.
I assume that is what you are using? Its harmless but should be fixed.

These only get compiled with enable-ec_nistp_64_gcc_128, but even with
that I don't see these warnings. Perhaps a gcc issue fixed in later
versions? I'm using gcc 4.9.2
