14*072a4ba8SAndrew Turner; Inconsistent behavior was detected for the following 2 cases.
15*072a4ba8SAndrew Turner; No exception is raised with certain versions of glibc. Functions
16*072a4ba8SAndrew Turner; approximated by x near zero may not generate/implement flops and
17*072a4ba8SAndrew Turner; thus may not raise exceptions.
