That looks like a similar problem though. std::asin(float) probably calls
std::__asinf, which apparently gives a different result to ::asinf.

If you comment out the call to test_float_overload() in main, it might fail=
 at
the same place in test_long_double_overload (or maybe somewhere else!)

Yeah, the cfarm is the only way I can test on Solaris, so that's why I use =
11.3
with -enable-obsolete.=
