        <pre>The C standard defect report #451 is related to this issue. The committe have

now answered defect report #451,

<a href="http://www.open-std.org/jtc1/sc22/wg14/www/docs/dr_451.htm">http://www.open-std.org/jtc1/sc22/wg14/www/docs/dr_451.htm</a>, and is seems like

LLVM/Clang will (in a future revision of the standard) be safe, doing this kind

of optimizations. The answer suggests introducing a notion of "wobbly" values,

that I think this will apply in this case. Therefore, I close this issue for

now.</pre>
