FWIW, I've run into this with -fsanitize=address and gcc 7.3 (minimized from
gdb/gdbtypes.c):
...
$ cat test.c
struct i
{
unsigned int i;
};
typedef struct i si;
extern const si const1;
extern const si const2;
si
foo (int c, int d)
{
si var = { 0 };
switch (c)
{
case 1:
switch (d)
{
case 2:
return var;
default:
return const1;
}
break;
default:
return const2;
}
}
$ g++-7 -O0 test.c -c -Wreturn-type -fsanitize=address
test.c: In function ‘si foo(int, int)’:
test.c:28:1: warning: control reaches end of non-void function [-Wreturn-type]
}
^
$ g++-7 -O0 test.c -c -Wreturn-type
$
...
