  • Version: v12.16.0+
  • Platform: Linux
  • Subsystem: v8

What steps will reproduce the bug?

Checkout to v12.16.0, build V8 and run tests:

# assume depot_tools is present in PATH
$ cd deps/v8
$ ./tools/node/fetch_deps.py .
$ ./tools/dev/v8gen.py x64.release --no-goma
$ ninja -C out.gn/x64.release d8 cctest inspector-test
$ ./tools/run-tests.py --gn --arch=x64 --mode=release mjsunit cctest debugger inspector message preparser

How often does it reproduce? Is there a required condition?

Every time, when the test is around 40%

What is the expected behavior?

Test should succeed

What do you see instead?

Additional information

git bisect points to 35f2892. Not sure we can fix it though. Opening the issue anyway so folks backporting V8 commits to v12 can find the error message.

@mmarchini Just for context, these failures have been noticed in the V8 CI runs before, but we agreed to be okay with this because these only affect flagged, experimental features. I agree that there’s not really something we can or should do, unless somebody really wants to dig into these failures.

I think those are also whitespace issues because of git node land (similar to what happened recently on master). I'll try to investigate it further.

@mmarchini would you be open to making a backport to 12.x to fix the whitespace issues?

@mmarchini

If that's the same issue, yes (it'll probably be a fresh PR to v12 instead of a backport though)
