Looking through godbolt.org the ASM generated with both
So why the array generated from getFoo() is 4 times bigger than

It isn't. You're casting one to int[] and not casting the other,
leaving it as void[], which writeln will interpret as just raw
bytes.
Since an int is 4x bigger than a byte, casting it to int shows
1/4 the number of ints.
But the actual array is the same.
