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.

small test case

lattner 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.

llvmbot commented 14 years ago

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