--- Comment #11 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
If you hit the assumption beyond what ABI mandates on some public symbol issue
in some older GCC version, then sure, if you have that public symbol defined by
ICC, it will misbehave.  But, if it is compiled with current GCC without your
proposed changes, it will work fine, newer GCCs don't assume anything beyond
ABI mandates alignments, unless they control the definition and uses bind
locally to it, but still align as optimization as much or more as older GCC
used to align.
With your proposed changes that would be no longer true.  What is so hard to
understand on it?
