Hello Jan! Could you please take a look at this? This looks to be frequent after your latest changes.

Thank you!

I'll take a look but for what it's worth, the test doesn't use bind() anywhere that I can see so it's likely unrelated to my changes.

Attachment: Bug 1819090 - Fix frequent cgc test failure in debug/optimized-out-03.js jit-test. r?jonco!

The test is checking that we get the "optimized out" value with the debugger API
for an Ion-compiled script, but gczeal can affect JIT compilations.
