reproducer C++ code with a lot of UB (mostly for GCC-13/12)

Actually, I found a reproducer C++ code for earlier GCC versions. The code is
filled with UB, though. I only used the new reproducer to check that the bug
exists for the 13.0.0-basepoint and disappears by cherry-picking the fix. I
didn't bother to check GCC 12, because backporting there is already closed,
IIUC.
