The error was (in the coverage build):

cp: cannot stat 'target/x86_64-unknown-linux-gnu/release/universal_cranelift': No such file or directory

Also, you'll have to drop the second commit (infra change).

The error was (in the coverage build):

Yes, I saw that. As you can see from the build logs, the coverage targets are building within seconds. This shouldn't be happening since projects are built from scratch for every sanitizers(address, coverage).

I was facing the same issue locally. The command build_fuzzers --sanitizer address worked fine, while the coverage was failing, so i reverted this commit deef8c5, and built infra images with following commands which solved coverage issue.

python3 infra/helper.py build_image --no-pull base-builder
python3 infra/helper.py build_image --no-pull base-builder-rust
python infra/helper.py build_image wasmer --no-pull
python infra/helper.py build_fuzzers --sanitizer coverage wasmer
python infra/helper.py coverage wasmer -- '-ignore-filename-regex=.*/rustc/.*'

I'm not sure what the root cause of this problem is, I saw the commit message about freezing container and reverted that, It could be related to that or something else.
