--- Comment #2 from Jonathan Wakely <redi at gcc dot gnu.org> --- GCC 4.4.7 gives an error: pod.cc: In function ‘void should_not_compile()’: pod.cc:6: error: jump to label ‘label’ pod.cc:4: error: from here pod.cc:5: error: enters scope of non-POD ‘non_pod_in_cpp03 x’ I assume GCC 4.5 stopped diagnosing it due to the revised specification which only cares about trivial constructor or trivial destructor, not PODness. So I suspect this change in behaviour is by design. The type in your program does not have non-trivial constructor or non-trivial destructor, so there is no danger in jumping over its initialization. Giving a diagnostic here would just be pedantic and unhelpful.
