--- Comment #2 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
But there is  && content_1[0] == '[' guard around it, but likely just no
optimization figures out that the inlined w_strlen (why aren't you using
strlen???) will always return at least 1 and thus the jump threaded variant
with zero length is dead.  I suppose instead of using w_strlen (contents_1) - 1
you could just use w_strlen (contents_1 + 1) and the warning could go away.
