The loop in MinimizeCrashInput has this check:

if (U.size() < 2) {
  Printf("CRASH_MIN: '%s' is small enough\n", CurrentFilePath.c_str());

So this assert gets hit when the current item is size 2.

Do you need help landing it?


pls change the summary to say smth like "saving small enough units". As far as I can see the issue was bigger than just artifact_path thing.
