--- Comment #4 from Rich Felker <bugdal at aerifal dot cx> ---
Andreas, in the case of hypot(NAN,INFINITY), (ha == 0x7f800000) is false, so
that branch won't be taken, and (hb == 0x7f800000) is true, but in that case,
fabs(y) gives the right value no matter what the value of x is. I think the
original bug report is likely correct. It's just not as "obvious" as the
reporter considered it.
