Which is a global variable, and has all the downsides of them. My advice still
applies.

Global arrays already have that extra indirection. I'm also hard pressed to see
how a large struct is going to suffer from an extra indirection to the array,
when it surely is going to suffer much worse from cache invalidation.

True, then it goes into the BSS segment, but the other issues still apply that
are not fixable by changing the compiler (i.e. executable bloat).
