N3639, which was voted into the C++14 committee draft today, adds a

"erroneous" can be any of:
- bound <= 0
- bound > some implementation-defined limit
- bound < number of initializers provided
Do we want to throw an exception if the stack hasn't got sufficient
space for the array? Then we need a fundamentally different interface
(probably a stack limit stored in a TLS variable or an alloca-like
function).
I should probably askon the standards list what the expectations are.
Uhm, is this about N3497? N3639 does not seem to exist yet (or if it
does, I'd appreciate someone sending me a copy).
