fenv not inherited from parent thread

Hi,

I'm trying to enable delivery of SIGFPE on floating point exceptions, which I'm able to do by manipulating the fenv, however the effect seems to be restricted to the current thread. According to
	http://en.cppreference.com/w/c/numeric/fenv
and verified on Linux, the fenv is inherited from the parent thread. It appears that that is not the case on MacOS X (Mavericks 10.9). Is there a way to have threads inherit their parent's fenv? Am I just missing something obvious?

Thanks,

	Niv
