$ cat main.cpp
struct foo {
unsigned i: 32;
};
int main()
{
foo f {};
return (f.i);
}
$ g++-snapshot -std=c++1y main.cpp
main.cpp: In function 'int main()':
main.cpp:8:15: error: cannot bind bitfield 'f.foo::i' to 'unsigned int&'
return (f.i);
^
-----------
The code is accepted if either the parens are removed (i.e. just return f.i;)
or when using -std=c++11.
