Random crashes in MCTS solver
🐛 Bug
We observe some random crashes on MacOS Github runners, and even more seldomly on Linux. But if pytest is launched from a bash shell on Windows (default shell is Powershell), crashes become reproducible. This helped to find that this is caused by UCT test, all other tests pass.
AddressSanitizer on Linux reports a new/delete mismatch, here is the full log:
==103597==ERROR: AddressSanitizer: new-delete-type-mismatch on 0x6020000d9450 in thread T0:
object passed to delete has wrong type:

I checked locally on windows from git bash with scikit-decide 0.9.7 from pypi. The bug is still there. To reproduce:
- on windows with git bash, create a python virtual environment with scikit-decide 0.9.7 + gym + pytest + simplejson
- edit "tests/solvers/cpp/test_cpp_solvers.py" to let only "uct" as tested solver, and remove the pytest.skip
- run it with
pytest tests/solvers/cpp/test_cpp_solvers.py ../test_skdecide/.

Also visible on a workflow when i reactivated the concerned test: https://github.com/nhuet/scikit-decide/actions/runs/6433572669/job/17471581478#step:12:728
For the moment I have no clue what the reason is, I'm still investigating...
The bug seems to disappear since last time i checked (i tried the procedure on windows git_bash as described above). Can be closed.
