--- Comment #1 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
>From https://gcc.gnu.org/gcc-4.5/changes.html:
Diagnostics that used to complain about passing non-POD types to ... or jumping
past the declaration of a non-POD variable now check for triviality rather than
PODness, as per C++0x.


See PR 37907.

And having an example would be useful too.  Because of the change between C++98
and C++11.
