--- Comment #4 from Derek Schuff <dschuff at chromium.org> ---
It might be possible to spin a new binary, I think we're looking into that.

But also I took a look at the symbols from the production binary (9.141.0.0), and I believe that ReadVarInt function is inlined into the function at index 7067 (indirectly via several layers, it appears; it's unfortunately quite a large function). A tool such as Wabt's wasm-objdump will give you the disassembly, and I assume JSC also tracks the function index for error reporting, etc. So if you have the ability to restrict just that function to a lower tier or something, it might be one way to check whether there are any differences in behavior.
