How do I open a glibc bug?
Although you say that the sign bit is set, thus you can have a negative NAN.
But it does not make much sense to allow this. A negative not-a-number is not
mathematically sensible. It wasn't the case in previous releases of the
library, so why did it just suddenly change? This change is causing some of our
code to break, so we would like to investigate it more before we are able to
change code to accommodate new changes.
