Sorry. I don't see this exercise as a complete waste of time

What it highlights is the fact that the warning infrastructure
we have in place is far from optimal for C++ in general (with
its heavy reliance on ilining and templates) and the standard
library in particular (especially with -Wno-system-headers).
We should make an effort to do better.
Setting aside the effort to clean up the library so that it can
be used even with -Wsystem-headers,
Yeah, it's an ongoing effort.
warnings about out of bounds
accesses should trigger even with -Wno-system-headers. If one
doesn't I'd tend to view it as a bug.
I agree. And __attribute__((__warning__(""))) too.
I added code to have some
trigger despite it but I'm pretty sure there are more places where
the middle end needs to do the same gymnastics to enable it.
