In MUONTriggerChamberEfficiency.C:

Former const char * arguments are now TString objects. This is why it is very common to build a const char * using the Form() function, such as Form("local://%s/OCDB", gSystem->pwd()), but this function points to a static circular buffer, that may be eventually overwritten between the Form() call and the const char * usage, leading to unexpected results. By using TString, we make sure that the buffer is safely copied before being overwritten.
