--- Comment #4 from Martin Liška <marxin at gcc dot gnu.org> ---
Yeah, the test is normally run with -r argument, so just run it with;
g++ /home/marxin/Programming/gcc/gcc/testsuite/g++.dg/lto/pr88049_0.C -flto
/home/marxin/Programming/gcc/gcc/testsuite/g++.dg/lto/pr88049_0.C:12:11:
warning: ‘a< <template-parameter-1-1> >::~a() noexcept [with
<template-parameter-1-1> = {anonymous}::f]’ used but never defined
12 | virtual ~a();
| ^
