PyConf generated configuration not reproducible due to B2OC line algorithm name assignments

When running

./build.x86_64_v3-centos7-gcc11-opt+g/run gaudirun.py -n -o /tmp/new3.opts ./Hlt/Hlt2Conf/tests/qmtest/sprucing.qms/test_spruce_all_lines_realtime.qmt

several times, each time to separate .opts files, the generated .opts files vary from run to run. For example:

Basically, the name assignment of algorithms is (still) not stable -- suspiciously the only ones affected are all algorithms in B2OC lines... (in addition, there is subsequent differences in eg. the generated DstData encoding table, but that is a result of the above differences).

So it looks like there is something B2OC specific which causes this problem

Note that non-reproducibility like this makes it hard to debug other problems.
