Sorry, but I cannot imagine how this could happen considering that 
one of them is alias to the other and thus they cannot be treated 
differently by the compiler (you can even interchange them for actual 
parameters and the compiler wouldn't notice it). If you have a short 
test showing otherwise, please post a bug report.
