--- Comment #1 from Martin Sebor <msebor at gcc dot gnu.org> ---
Confirmed with the following simplified test case. Just bitwise compound
assignment operators seem to be affected. This seems to ring a bell but I
can't find a duplicate bug. All releases all the way back to 4.1 have this
bug, including trunk (GCC 8.0).
$ cat t.C && gcc -S t.C
template <typename T>
void operator^= (T&, int);
enum E { };
void f (E e)
{
e ^= 2;
}
t.C: In function ‘void f(E)’:
t.C:8:5: error: invalid conversion from ‘int’ to ‘E’ [-fpermissive]
e ^= 2;
~~^~~~
