Can I see a command line and a complete cpp file that triggers the warning?
You've already been given the example where including checked_delete before exception_ptr is enough to generate the warning.
It has also been pointed out that if you're not getting the warning, you're probably not using a real gcc 4.7.0.
Really? olaf@testing:~$ g++-4.7 -c -Wall demo.cpp $ cat demo.cpp #include <boost/checked_delete.hpp> #include <boost/exception_ptr.hpp> $ g++-4.7 -c -Wall demo.cpp -Wdelete-non-virtual-dtor $ g++-4.7 -v Using built-in specs.
