[Bug c++/78826] jump bypasses non-POD

--- 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.
