Hmm, I would almost want to go on a limb and say this was caused by the patch
for PR 21166.  Can you try to revert that patch and try the mainline compiler?

Of course that's it.  Thanks for spotting this!

Maybe I am missing something, somewhere, what does the missing DECL_PACKED do?
Do you have a simple compile time testcase which fails with 4.1.0 but passes
with 4.0?

Advertise that the field is bit-packed?

See comment #1 and #2.

ABI breakage: showstopper.

Confirmed.

I'm seeing on x86_64:

FAIL: tmpdir-gcc.dg-struct-layout-1/t026 c_compat_x_tst.o-c_compat_y_tst.o
execute

Thanks.  The compat and struct-layout-1 testsuites are clean on sparc64 when
run
in mirror mode, but not when run against 4.0.x.  This failure was distilled
from the failure of the struct-align-1 test in the former testsuite.
