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:

ERROR: jack-1.19.22-r0 do_configure: Error executing a python function in exec_func_python() autogenerated:

The stack trace of python calls that resulted in this exception/failure was:

"Semi-reliably", i.e. about 50-50 or 60-40 percent failure vs success rate.
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.
