What's important is not support lifetime, but whether or not the warning persists through version 4.1.2, 4.1.3, etc.

The current markers tend to exist for a class of problems that gcc fundamentally has a tough time "seeing." Different optimizer behaviors from compiler version to compiler version are just noise[1].
