Looks like a schroedinbug. The .s file from before ("pass") is
obviously wrong, but the right value *happens* to be in the right
register at the right time to cause the test to pass.
The non-related patch perturbed the compiler just enough to alter the
way the program was optimized (strange but true), which changed the
"just happens" into a "doesn't".
