Would you mind showing which commit fixed this? I'm curious about it. I searched in the git log, but nothing mentioned this bug number. Now I can come to my original intent, which is asking if this code is suppo= rted by GCC, as in Does this code have defined behavior under GCC? Does it need and -f flags to be defined? Or is it just undefined behavior? I ask because this code exists in a real project.=
