--- 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]
         exit: ;
         ^~~~
