Jeff, I don't expect to have the cycles to reimplement this patch
using the Ranger APIs before stage 1 closes. I'm open to giving
it a try in stage 3 if it's still in scope for GCC 11. Otherwise,
is this patch okay to co

Overflowing the size of a dynamic allocation (e.g., malloc or VLA)
can lead to a subsequent buffer overflow corrupting the heap or
stack. The attached patch diagnoses a subset of these cases where
the overflow/wraparound is still detectable.
Besides regtesting GCC on x86_64-linux I also verified
