As does icc.

I can't see why the code would be invalid if one accepts that
  T bar;
is the declaration of a function pointer 'bar'. In that case, you
simply have an invalid function pointer and calling it should yield
a segfault, just as you get.

Now, here's a different interpretation that icc actually takes: it says
that
  T bar;
is the declaration for a function with name and signature
  int bar();
and the code will yield a linker error when compiled.

In any case, can you clarify why exactly you think the code should be
rejected?

W.
