My buddy just tried to compile a OOT module against the latest "maint" of Gnu
Radio, and got treated to the above explosion. It looks like
the C compiler is confusing the version of math.h in the Gnu Radio codebase
with the libc version, and then things go all explody.
He's running on an x86_64 Ubuntu 12.04 system.
The OOT module was produced using "gr-modtool" just a couple of weeks ago.
