[Bug c++/44122] New: Confusing error: cannot convert 'T*’ to ‘T*’

["ppluzhnikov at google dot com" <gcc-bugzilla at gcc dot gnu dot org>]

Here is the complete error message:

g++ -c t.cc
t.cc: In function ?int bar()?:
t.cc:8:18: error: cannot convert ?Py_ssize_t*? to ?Py_ssize_t*? for argument
?1? to ?int foo(Py_ssize_t*)?

How is that even possible?

cat t.cc
typedef long Py_ssize_t;

int foo(Py_ssize_t *);

int bar() {
  typedef int Py_ssize_t;
  Py_ssize_t pos;
  return foo(&pos);
}

Suggested improvement:

t.cc:8: error: cannot convert '{bar}::Py_ssize_t* [int*]' to 'Py_ssize_t*
[long*]' for 1st argument to 'int foo(Py_ssize_t*)'
