--- Comment #2 from Oliver Rosten <oliver.rosten at googlemail dot com> ---
With gcc 16, this no longer needs -ftrivial-auto-var-init. In C++26 mode the
same .DEFERRED_INIT is emitted for erroneous behaviour (P2795), so the testcase
in comment 0 warns with just:
$ g++ -std=c++26 -O1 -Wall -c uninit.cpp
uninit.cpp:5:30: warning: 'D.2801' is used uninitialized [-Wuninitialized]
It does not warn with -std=c++23, at -O0, or with -std=c++26
-ftrivial-auto-var-init=uninitialized.
gcc 16.2.0, aarch64-apple-darwin
