Oh wow! This was due to lack of build-isolation! Let me explain, the error was triggered when running conda build without the --no-test flag. That is the base environment has conda build installed and will make a test environment and after building the package execute the tests in a special (supposedly isolated) test environment. However this causes the bug above. The fix is to do the testing in a fresh GHA job using the command conda build --test llvmlite*.conda on the previously generated artifact. In that case, we are also using the test functionality of conda build but the test passes!

The fix is in commit:

017554d

and the successful run:

https://github.com/esc/llvmlite/actions/runs/13097834052

What could be causing this?

The issue is genuine, it seems. Splitting the build and test wasn't the issue, the test job was using the wrong test command -- but that had an exit code of 0 -- so the failure wasn't detected, because the tests didn't actually run.
