That is expected, because the program is testing Inf/Nan and I wanted
to generate an infinity from an actual computation. For the tests I
use mask-all.
If you would like to make the tests work without it, you could do
something like this,
#ifdef INFINITY
inf = INFINITY;
#else
int = exp(1.0e10);
#endif
(Similarly for NAN). This assumes that macro definitions are actually
valid.... but check ahead and see if there are other tests ( in other
directories) which generate floating point exceptions (I think there
are some in specfunc/, but maybe they can be eliminated easily). It
would only make sense to start changing these if the whole test suite
can be tidied up to avoid them.
