--- Comment #2 from Marek Polacek <mpolacek at gcc dot gnu.org> ---
gcc34 / 44 / 45: 
v.c: In function `main':
v.c:8: error: subscripted value is neither array nor pointer

gcc4.6+ ICE.

g++ 4.6 and 4.7 give
v.c: In function ‘int main()’:
v.c:8:50: error: invalid types ‘u8x16_t {aka __vector(16) unsigned char}[int]’
for array subscript

And g++ 4.8 and newer ICE.

So looks like a regression and it seems we want to do what the FEs were
aleready doing in the past.
