PR3248 also provides the relevant (C) quotation here:

Per C99 6.5.3.4p2, "If the type of the operand [of a sizeof] is a variable
length array type, the operand is evaluated; otherwise, the operand is not
evaluated and the result is an integer constant."

The argument type you provided isn't variably modified, so the operand to
sizeof is not evaluated, merely used to figure out the type to determine the
size.
