Additional information

According to https://github.com/nodejs/reliability/issues?q=is%3Aissue+is%3Aopen+%22test-esm-loader-hooks-inspect-wait%22 this started showing up from the 9 August reliability report.

This is flaky on Ubuntu 22.04 as well: https://ci.nodejs.org/job/node-test-commit-linux-containered/45976/

I can reproduce locally (on macOS), it's very rare (2 failures in 9999 runs). SIGSEGV means we're doing some kind of unsafe memory access, which sounds like a real bug 🤔

[avivkeller]

FWIW I got ~11 failures in 1000 runs on Linux. (after @lpinca's PR)

However, I'm unable to reproduce in v22.8.0.

https://github.com/nodejs/reliability/blob/main/reports/2025-01-27.md shows this still happening on FreeBSD and SmartOS while #56792 (comment) is an instance of this failure on AIX.

#54802 marked this test as flaky on Linux -- I'll open a PR to extend the flaky status to the other platforms.
