[Bug c++/37854] New: No error when creating a variable from itself

["julien dot sagnard at gmail dot com" <gcc-bugzilla@gcc.gnu.org>]

If I try to compile this code:

class X {};

int main {
  int i = i;
  X x = x;
  X y(y);
  return 0;
}

With:
gcc -Wall main.cpp

There is no error and no warning.
