Yes; it actually evaluates the entire expression (including the use
of the sizeof operator).

The expression is incomplete; but with the expression you gave and
assuming we're just missing a closing parenthesis, I don't see why
it would need to allocate memory in the inferior. Perhaps you've found
a bug.
