What steps will reproduce the bug?

Attempt to run a recent node v18.0.0 nightly (e.g. https://nodejs.org/download/nightly/v18.0.0-nightly20220315a01302b8df/) on Ubuntu 18.04 or earlier.

Ubuntu 18.04 only has glibc 2.27:

root@5d282713443e:/# /lib/x86_64-linux-gnu/libc.so.6
GNU C Library (Ubuntu GLIBC 2.27-3ubuntu1.5) stable release version 2.27.

I haven't worked backwards to find out which nightly build introduced this. I can do so if that would help.

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

Reproduces every time on Ubuntu 18.04.

What is the expected behavior?

Nightly builds of v18.0.0 from a week or two ago (last I checked) ran fine on Ubuntu 18.04. My expectation is that nightly builds would continue to do so. However, I don't know what the policy is for supported Linux glibc. The building notes (https://github.com/nodejs/node/blob/master/BUILDING.md#platform-list) suggest glibc >2.17 should suffice for building.

Did something change in how the node.js nightlies are being built? Was this change to a newer minimum glibc version intentional? (Apologies if this is the wrong place to ask.)

What do you see instead?

Node crashes.

This is intentional -- we're moving compilation of Node.js binaries from CentOS 7 to RHEL 8 for Node.js 18. I'll be opening an update to https://github.com/nodejs/node/blob/master/BUILDING.md#platform-list later in the week. Unfortunately, as you have discovered, this includes a glibc version bump that excludes Ubuntu 18.04 (18.10 and 20.04 should work).

@richardlau Okay. Thanks for the info!
