These checks were useful while investigating other issues;
using empty Local<>s can be very un-debuggable, because that
typically does not lead to assertions with debugging information
but rather crashes based on accessing invalid memory.

Checklist
  • make -j4 test (UNIX), or vcbuild test (Windows) passes
  • commit message follows commit guidelines
