--- Comment #7 from Marek Polacek <mpolacek at gcc dot gnu.org> ---
I know you can't jump into a statement expression but that's not what's
happening here. The kernel uses this trick to get the current address for
error messages:
#define __this_address ({ __label__ __here; __here: barrier(); &&__here; })
and they will have to disable the warning completely because of it. The manual
for -Wdangling-pointer also talks about pointers to *objects* and labels aren't
objects.
