the attached testcase shows that sizeof(int) is not identical to a compile time
constant of 4.
the first testcase uses sizeof(int) as a bound check, and somehow the call to
the non-existing function is not optimized out.
in the second testcase sizeof(int) is replaced by "4" and the optimization
suddenly works.
