Well, okay, that implication didn't look that obvious. Sorry for the constant
bug reopening, it was not my intent. And thanks for the clarifications!

I think there is an issue with the way gcc uses the __attribute__ information
when generating SIMD load instructions during auto

I don't think this is a user error. Some attributes might be declared aligned
inside a structure, without any specifications that every instanced objects
must be themselves aligned

Moreover, the test case runs fine without any automatic vectorisation and
crashes when it is applied, so from my point of view there is something wrong
with this optimisation!
