--- Comment #6 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
Fixed the error-recovery bug on the trunk, but the ice on the #c4 testcase =
is
still there (and the question is if it is valid or not).  If it is valid,
probably the FE or gimplifier needs to turn that cast to VLA union into
creation of a VLA temporary and assigning the cast operand into the right f=
ield
of it.=
