[Bug c++/6424] [DR 339] sizeof() with overload resolution

Actually, icc doesn't handle this at all: it rejects the code 
with the error message 
 
g/x> icc -c x.cc 
x.cc(10): error: no instance of function template "f" matches the argument 
list 
            argument types are: (int) 
    f(1); 
    ^ 
 
The same happens if I explicitly say f<int>(1) in the call in main(). 
 
 
I never quite understood why we have to mangle the return expression 
for examples like this, i.e. mangle A<sizeof(xxx((T)0))> instead of 
A<1>. I know that the ABI says so, but can someone point me to a 
simple explanation _why_ it says so?
