```c++
#define S(a) switch(a){ default }
#define D default
#define C(x) case x
int foo(int a) {
switch(a) {
default
}
S(a);
switch(a) {
D
}
switch(a) {
C(10)
}
}
```
```console
<source>:13:17: error: expected ':' after 'default'
13 | default
| ^
| :
error: expected ':' after 'default'
<source>:19:11: error: expected ':' after 'default'
19 | D
| ^
| :
<source>:23:14: error: expected ':' after 'case'
23 | C(10)
| ^
| colon
4 errors generated.
```
the second emitted error does not have a valid source location.
Seems like this only happens if the entire switch is expanded from a macro.
