--- Comment #1 from Martin Sebor <msebor at gcc dot gnu.org> ---
Confirmed. GCC never accepted the test case so it's not a regression.
$ cat t.C && gcc -S -Wall -Wextra -Wpedantic t.C
void f() {
goto exit;
[]() -> void {
exit: ;
}();
exit: ;
}
t.C: In lambda function:
t.C:4:17: warning: label ‘exit’ defined but not used [-Wunused-label]
exit: ;
^~~~
t.C: In function ‘void f()’:
t.C:2:14: error: label ‘exit’ used but not defined
goto exit;
^~~~
t.C:7:1: error: duplicate label ‘exit’
}
^
t.C:6:9: warning: label ‘exit’ defined but not used [-Wunused-label]
