"Nothing" as in I should withdraw this patch? Surely not?

The behavioral difference my patch brings would be:
debug:  assert with useless information -> assert with useful information
release:  crash with useless report -> print useful information, continue

As I wrote, I can compromise the second part to:
release:  crash with useless report -> print useful information, exit VM
