4 | Subject: [PATCH] Do not pass null pointer to freeaddrinfo() | ||
5 | |||
6 | Passing null pointer as input parameter to freeaddrinfo() is undefined | ||
7 | behaviour, some libcs e.g. glibc might just call free() which does | ||
8 | accept null pointer but other libcs e.g. musl might not and instead | ||
9 | cause the program to segfault. Therefore do not rely on undefined | ||
10 | behaviour instead make it deterministic | ||
11 | |||
