>=node-16.0.0: failed test # 12 in parallel/test-repl-history-navigation

[mkszuba]

• Version: 16.0.0, 16.1.0
• Platform: Linux

What steps will reproduce the bug?

For me, it occurs when I running the Node.js Python test suite:

python3.8 tools/test.py --mode=Release --flaky-tests=dontcare -J message parallel sequential

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

Always.

What is the expected behavior?

All tests pass.

What do you see instead?

One of the tests fail, see the attachment for its output.

That's something we stumble upon on #38141 (review), I'm unsure what's causing this behaviour and why it doesn't reproduce in a consistent way. Have you built node on your local machine or are you getting it from somewhere else? Any chance you could share what configure options have been used on compilation?

[mkszuba]

I build it locally, with the configuration stage invoked by:

python3.8 configure.py --prefix=/usr --dest-cpu=x64 --shared-brotli --shared-cares --shared-libuv --shared-nghttp2 --shared-zlib --shared-openssl --openssl-use-def-ca-store --without-dtrace --without-inspector --with-intl=full-icu
