Example of a even small one (30 token duplicated):
Found a 11 line (30 tokens) duplication in the following files:
Starting at line 2551 of D:\DOWNLOADS\Python-3.0\Python\Python-ast.c
Starting at line 3173 of D:\DOWNLOADS\Python-3.0\Python\Python-ast.c
if (PyObject_SetAttrString(result, "ifs", value) == -1)
goto failed;
Py_DECREF(value);
return result;
failed:
Py_XDECREF(value);
Py_XDECREF(result);
return NULL;
}
