That's a massive test case. Do you think you could reduce it?

Quuxplusone commented 14 years ago

At this point, we need very small reduced testcases to drive C++ forward. If we can't do that, I recommend closing this as invalid.

Quuxplusone commented 14 years ago

We didn't add any built-in candidates for the array subscript, because only pointers trigger that. Now arrays are decayed to pointers for this purpose.

Fixed in r86140.
