Description Joseph Myers 2012-12-03 17:34:12 UTC 
The ARM implementation of feenableexcept should test whether the requested exceptions were set, and return -1 for failure if not, much like the fesetenv problem that was bug 14866.
Comment 1 Joseph Myers 2012-12-03 17:35:36 UTC 
(VFPv3 and VFPv4 do not support trapping exceptions, so feenableexcept will fail to enable them on processors with those VFP versions.)
Comment 2 Joseph Myers 2013-06-17 17:22:32 UTC 
Fixed for 2.18 by:

    Make ARM feenableexcept detect failure (bug 14907).
