In recent AnalysisBase versions (25.2.42 or higher) one could not anymore submit jobs to the grid due to an error

Traceback (most recent call last):
  File "<string>", line 1, in <module>
TypeError: Could not find "SwapWithObjAtAddr<std::any>" (set cppyy.set_debug() for C++ errors):
  void ROOT::Internal::SwapWithObjAtAddr(any& a, intptr_t b) =>

Fixes MR: !76133 (merged)

This MR fixes the issue.

  • I tested the fix with a minimal reproducer of the problem as discussed in the following comments comment1, comment2

  • Then did a sucessful grid submission that you can find here some jobs already succeeded like already at 20% and I checked the log files output is as expected e.g. one log file link

I am tagging here all the relevant persons and flagging as urgent and RC Attention Required since this touches a Core package @akraszna @krumnack @ademaria @ssnyder

Tagging also for info @mungo, @zhcui @alpleban (feel free to tag more people if they are concerned by this issue)
