Those certainly don't look healthy..
There were a few of those also in 7.5.2 build with the same buildroot
and system libraries, just a lot fewer. Any idea how to find the cause?
My strong assumption is that such -Walloc-size-larger-than are all false
positive warnings emitted by a poor version of GCC. (There are lots of
such over-eager warnings getting implemented in recent versions of GCC,
with lots of known false positives. Just every specific version of GCC
and specific set of GCC command line arguments emits a different set of
bogus warnings when building LO.)
