[C++] isVirtualBaseClassOf gets stuck

[h0nzZik]

The program

struct B {int x;};
struct C : B {};

int main() {
    C c;
    c.x = -1;
    B *rb = &c;
    static_cast<C *>(rb);

gets stuck:

isVirtualBaseClassOf(
  tcpp(quals(`.Set`(.KList)),`.Set`(.KList),classType(classId(`GlobalNamespace`(.KList),classSpecifier(`Struct`(.KList),`Identifier`(#token("\"B\"","String")),`.List{"_,__CPP-DYNAMIC-OTHER-SORTS"}`(.KList))))),
  tcpp(quals(`.Set`(.KList)),`.Set`(.KList),classType(classId(`GlobalNamespace`(.KList),classSpecifier(`Struct`(.KList),`Identifier`(#token("\"C\"","String")),`.List{"_,__CPP-DYNAMIC-OTHER-SORTS"}`(.KList)))))
)
