Commit 8b59cd81dc5 ("kbuild: ensure full rebuild when the compiler is updated") added the environment variable CC_VERSION_TEXT, parse_from_string() doesn't expect a string in value field and this causes the failure below: [iha@bbking linux]$ tools/testing/kunit/kunit.py run --timeout=60 [00:20:12] Configuring KUnit Kernel ...
