Upon further experimentation, I agree with Christian's statements. I have attached a simple demo case illustrating the different codes.   I no longer have the original code that led me to discover this optimization, but I will  keep my eyes peeled for future occurrences.    However, this reveals a bug either in GCC or GDB: GDB was not aware that my object  instance was silently optimized into a reference.  (I take it this happens only if GCC  can determine that obj is the only object that will EVER be returned from the method.)  Is this a case of GCC not emitting debug info that describes obj as a reference, or is  this a case of GDB not picking up on something that was there?    I am using GDB 5.3.
