What I mean is this:
// first example, unrelated to the DMD codebase
extern(C++) class Foo {}
void main ()
{
auto a = new Foo;
assert(a.classinfo is null);
}
// second example, somewhere inside the DMD codebase
auto a = new IntegerExp(0);
assert(a.classinfo !is null);
Both of the above assertions pass. My question is why the second assertion pass.
