Cppcheck 2.18 False positive constParameterReference

[Félix-Antoine Constantin]

Running cppcheck cppcheck --enable=style test.cpp on the following code snippet will result in an error .

using IntPtr = int *;

int* foo(IntPtr bar)
{
  return bar = 0;
}

test.cpp:3:17: style: Parameter 'bar' can be declared as pointer to const [constParameterPointer]

The problem is that since the type is defined through using (the same behaviour would be observed if I was using typedef), it is not possible to add const here, since it will result in the underlying type int *const rather than const int*.

Thanks for your report. I filed https://trac.cppcheck.net/ticket/14539 about it.
