Description
I have spent hours trying to reproduce this outside of my crater-but-miri project: https://github.com/saethlin/miri-tools and I have had no success yet. Maybe I'll try to reduce this further into something that's easy to reproduce.
What I have learned so far is that it appears that I need:
export TERM=xterm-256color
export MIRIFLAGS="-Zmiri-disable-isolation -Zmiri-retag-fields"
cargo miri test -- --test-threads=2
But again, I swear I've manually spun up the same setup in the Docker containers that project spins up and yet, no ICE when doing things manually.
