    Problem Text
    This test may fail on implementations where the variable i is
    optimized out of existence and causes the test to fail.

    The variable i is local and never referenced other than to be loaded.
    Since the test code does not protect against dead variable removal, the
    variable maybe optimized out. As a result, the expected signal may
    not be received when the test is in a tight while loop that provides
    no opportunity to receive the signal.

    The variable i should be declared volatile or make i a global variable
    either one of which will disallow this form of optimization. You
    could also pass i to another function.
