Status: UNCONFIRMED
Severity: normal
Priority: P3

GCC 11 started to accept
void b()
{

e:
int f;
}
which was previously rejected as
t.c: In function 'b':
t.c:5:3: error: a label can only be part of a statement and a declaration is
not a statement
5 | int f;
| ^~~
t.c:4:1: error: label at end of compound statement

and which clang also rejects:
t.c:5:3: error: expected expression
