Code:
struct _a
{
    int _a1;
    uint64_t _a2;
}

to
Code:
struct _a
{
    uint64_t _a2;
    int _a1;
}

Note that I swapped the order of the fields in the structure.

By defining the structure with the smaller elements first, if the structure is packed tightly, as it likely is under optimization, you're likely violating an address restriction on the value when you pass it like that.
