Sholdn't there be a test that checks that the segment alignment is as
expected?

What happened to the earlier concerns that the presence of
PT_GNU_PROPERTY will break some existing installations?

I would strongly recommended to try harder to get consensus here.  I do
not want to be a in a situation were we revise ABI again two years from
now.

Thanks,
