I couldn't understand how the test could be optimised out since it determined whether a constant was returned or the value of a global variable but in looking further it's possible that for that logic flow the global variable would not have been written to yet, making both sides of the test return the same value. Or to put it another way, dumb programmer mistake strikes again.
