I am not a fan of this at all... In my book these warnings show an error in our code. They should not be ignored!

So @fwinkl, I guess I'll be fixing this in another way in the next days...

Either way is fine with me. I am also happy to revert this again if you prefer.

Parts of it are fine. The suppression of the undefined behaviour sanitiser is fine. It is just that these warnings appeared from xAODRootAccess because of a change in the behaviour of StoreGate. Which I don't want to "solve" by introducing suppression rules in all unit tests that use xAOD::TEvent... (Plus, printing warnings every time a user reads a DxAOD like that, is really not a good thing...)

added sweep:ignore label
