<pre>How to reproduce:
```
#include <iostream>
struct Acc {
int a;
};
struct Buu {
int b;
};
struct Foo {
const Acc& acc;
Buu& buu;
};
void printInfo( const Foo& ) {
std::cout << "hi!" << std::endl;
}
void call( Buu& buu ) {
Acc acc = { 1 };
Foo foo = {
.acc = acc,
.buu = buu,
};
std::cout << "before" << std::endl;
printInfo( foo );
std::cout << "after" << std::endl;
}
void noCall( Buu& buu ) {
Acc acc = { 1 };
Foo foo = {
.buu = buu,
.acc = acc,
};
std::cout << "before" << std::endl;
printInfo( foo );
std::cout << "after" << std::endl;
}
int main() {
Buu buu = { 2 };
call( buu );
noCall( buu );
return 0;
}
```
Repeats at least in 3.7.0 through 3.9.0.
Output:
```
before
hi!
after
before
after
```
Yes, it is not a C++ standard code, but Clang does not issue a compile error
when deleting the function call.</pre>
