> In my opinion, the warning should be given

Nobody contradicted you, we agree that it would be good to issue the warning.
We already know about this issue (there are duplicates you can search for in
bugzilla). The reason we haven't fixed it yet is that it is hard (we don't want
to generate tons of false positives, or to pessimize code generation, etc).
If you know how to fix it, contributing a patch to gcc-patches@gcc.gnu.org
would be welcome.
