Review comment:
I think `raw_etags_len` is still uninitialized. I usually don't define
multiple variables on one line to avoid this confusion.
```c++
#include <iostream>
int main() {
int a, b = 1;
std::cout << a << std::endl;
std::cout << b << std::endl;
}
```
```
foo.cc:4:18: warning: variable 'a' is uninitialized when used here
[-Wuninitialized]
std::cout << a << std::endl;
^
foo.cc:3:10: note: initialize the variable 'a' to silence this warning
int a, b = 1;
^
= 0
```
