>Description:
Doing meta programming without __if_exists (as in VC, when
are you going to add it?) takes clever tricks. The only
solution I could come up with results in internal compiler
error :-(. Here is a minimal program that causes the bug:
struct A { int x; };
template <class T> struct B {
typedef typeof(T().x) y;
};
int main(void) {
B<A> dummy;
return 0;
}
>How-To-Repeat:
Just compile the above lines.
