The float denormal macro defined in Freeverb/Components/denormals.h
doesn't come out too well with recent gcc - I replaced it with this
(which turned up on this list during a discussion about denormal
handling):

static inline float
undenormalise(volatile float s)
{
	s += 9.8607615E-32f;
	return s - 9.8607615E-32f;
}

It should be fine after that.
