Replacing floorf() in the program by:
fabs()
rintf()
sqrt()
expf()
log10f()
logf()
cosf()
powf(,)

doesn't crash.

The only two functions I found to crash are floorf() and ceilf().

Replacing all floats by doubles and using floor() or ceil() doesn't
crash either.

So it really seems to be in the floorf() and ceilf() code.
