--- Comment #3 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
I think .b is not a problem, that should be 0, but there are 17 bits of pad=
ding
at the end of the structure, and that has unspecified bits.
So, I think the testcase is invalid and normally succeeds only because the
gimplifier decides to zero the whole structure instead of initializing .b t=
o 0.

Of course, it would be nice to find out what the r11-2709 code does exactly=
