We've had the testcase below in autovect-branch for a while, testing

enough to keep it alive?
It should be but from the looks of it. For some reason in alias2, we
don't say
D.503_30 points to anyoffset in &e unlike before. You might be able
to generate a
C testcase for this too.
I should mention that we have in alias2:
D.503_30 = &e.d[D.502_29];
which points to anyoffset in &e.
