Summary: Failed equality of structs with string field

This program produces a runtime assert error, it's a bug:
struct Foo {
string s;
}
void main() {
Foo b1 = Foo("hello".idup);
Foo b2 = Foo("hello".idup);
assert(b1 !is b2); // OK
assert(b1 == b2); // line 8, error
}
With DMD 2.056head it gives:
core.exception.AssertError@test(8): Assertion failure
The equality among structs has to call the string equality of their fields. The
"is" operator has to compare the structs bitwise.
