The fix posted here affects only 'read', unless I'm missing
something...

That's okay. If you tell that fixing the issue with 'read' solves the
problem described in bug#63752, I will merge them. But if some
problems caused by _FORTIFY_SOURCE still remain after fixing 'read',
then bug#63752 is more general, and I think they should remain
separate, so that when we close this one, the other one stays open.
