Crash on snapshot deserialization during bootstrapping

[santigimeno]

Version

v20.10.0

Platform

Linux sgimeno-N8xxEZ 5.15.0-89-generic #99-Ubuntu SMP Mon Oct 30 20:42:41 UTC 2023 x86_64 x86_64 x86_64 GNU/Linux

Subsystem

What steps will reproduce the bug?

Running test/parallel/test-domain-error-types.js under load would rarely cause this. To make the crash happen more consistently I had to run multiple instances in parallel while reducing the gc-interval:

export NODE_SKIP_FLAG_CHECK=1
for i in $(seq 1 10); do out/Debug/node --gc-interval=10 --stress-compaction test/parallel/test-domain-error-types.js & done

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

Using the command above, mostly always. It seems having the gc kick in while deserializing the snapshot is causing the crash.

What is the expected behavior? Why is that the expected behavior?

Not crashing.

What do you see instead?
