--- Comment #3 from Richard Biener <rguenth at gcc dot gnu.org> ---
With just -ftrivial-auto-var-init=pattern I see and ICE in
during GIMPLE pass: lower
vbase8-22.C: In function 'int main()':

cut&pasting all arguments you list doesn't change that, so ...? How did you
configure GCC? I have --target=arm-none-linux-gnueabihf --with-float=hard
--with-cpu=cortex-a9 --with-fpu=neon-fp16
