This is perfectly legal, and will vary from system to system  

Presumably this was run on a system, where intergers require alignment
at a multiple of 4 bytes. In this case, struct X must be padded out to
a multiple of 4 bytes, in this case 8 bytes. The 3 unused bytes in an
object of type X, exist, but their contents are meaningless.

The padding ensures that the integer subobject i, will be properly
aligned if you define an array of X.
