It's not an issue in vercmp_string_op itself,
I already know this.
Apparently you haven't read my mail fully for the conclusion.
but the version value it gets from waf --version isn't just the version itself but also
SyntaxWarning from waf.
That is not a problem in itself as the preceding call only collects the stdout:
result = subprocess.check_output([python, wafbin, '--version'], cwd=subsrcdir,
stderr=subprocess.STDOUT)
SyntaxWarning goes (or should go) to stderr.
When this part is moved into a minimal test case, there is no error at all.
The error only happens inside bitbake and there was no such problem
with Python 3.11.x or earlier.
Ergo, the problem must be a Python 3.12 issue.
The actual version here is python3-3.12.1-2.fc39.x86_64 for me.
So you need to update waf in jack not to trigger SyntaxWarning when waf
--version is called.

Hi,
Just a FYI.
After the bitbake-server getting stuck after bitbake exited
with Python 3.12 issue was fixed, here's another one.
This time it's semi-reliably triggered by the jack recipe
in meta-openembedded:

Usually the second run succeeds after a failure.
I copied vercmp_string_op() and all others called by it
from bitbake/lib/bb/utils.py into a new python script as a
minimum test case. Running this script inside a locally
cloned jack git repository has 100% success rate.
It looks like an internal Python "flake" issue.
