--- Comment #1 from Jonathan Wakely <redi at gcc dot gnu.org> ---
This is because warnings are suppressed by default in system headers, and the
undefined delete operation occurs in a system header. You get the warning if
you use -Wsystem-headers
I don't see an easy way to force the warning to always be emitted though.
