Is this a bug or an acceptable value?

Current solution was to mark this test as flaky on Linux.

From digging all day into the wierdness that happening in macOS it seems that the different V8_IMMEDIATE_CRASH implementations are doing different thing on different platform and for different compilers on the same platform, so maybe it's not that strange 🤷‍♂️ especialy since Alpine Linux does not use glibc but rather musl libc

I still have SSH access to one of the machines, and this is how far I’ve traced it:

$ ./node -e 'process.abort()'
Received signal 6
[end of stack trace]
Segmentation fault (core dumped)

It appears the segfault occurs within abort(). I’ll try to see what else I can find out, but the docker container being a docker container makes debugging a bit more difficult than what I’m used to.

I am pretty sure V8_IMMEDIATE_CRASH is not involved here. I am no longer pretty sure. 😄
