[False positive] Portability: Returning an integer in a function with pointer return type

[Toni Neubert]

The following code creates a false-positive:

int* f()
{
  auto* i = static_cast<int*>(malloc(1));
  return i;
}

[test.cpp:4]: (portability) Returning an integer (int/long/etc) in a function with pointer return type is not portable across different platforms and compilers.

The problem is, CppCheck tracks only the type of auto but not the complete type auto *

I fail to reproduce with the latest cppcheck.

Well it says that i has type signed int * as far as I see. Not sure maybe you have an old Cppcheck version that did not track this properly.

Ah, I see, thank you.

We are using CppCheck 1.9 at the moment. I double checked the issue with the online demo (http://cppcheck.sourceforge.net/demo/) but this seems to use also an older version.
