Yes, that's the main reason I want to make this change.

Yes, I think it should.

You can read my notes on these "debug mode lite" checks at
https://gcc.gnu.org/wiki/LibstdcxxDebugMode (including "This should be
discussed with Glibc and security teams" and I specifically had you in
mind when I wrote that :-)

Your thoughts would be much appreciated, especially regarding
_FORTIFY_SOURCE and which kind of new checks you think would be
appropriate to add.
