My patch (31dc8730af585d8e13021484752fb20decae0661) fixes the testcase and libm already
have cover test to check for the issue, the check 'asin (0x0.ffffffffffffp0L)' was the
test that triggered the issue for me. I believe what need to be done is add the bug
number in the ChangeLog and in the NEWS.
I'll update the bug report with these informations.
