Hi Lang,
clang crashes when I compile the following code with "-Xclang -ast-dump”:
class Base {
public:
virtual void operator()() {}
};
class Derived : public Base {
public:
void operator()() override {}
};
If I change “OS << D->getName()” to “OS << D->getNameAsString()”, the crash
disappears.
Can you take a look please?
