You might want to verify that yourself, before making that claim.

I've already seen handfuls of bugs in other software that gcc-4.8.0
kicks up, that 4.7.x did not. - so unless you are _positive_ it's a
gcc bug ~ i wouldn't be asserting that it is, since it's also a
possibility that your code (like any code) may contain bugs..

just my 2 cents
