Comment (by nickm):
I don't think there is an actual difference before and after the fixup.
Try this demo:
{{{
#include <stdio.h>
int
main(int c, char**v)
{
struct foo { char array[10]; };
struct foo x;
printf("%p\n", x.array);
printf("%p\n", &x.array);
return 0;
}
}}}
Note that both pointers are the same.
I'm happy to merge this now, or wait for dgoulet.
