Memory Leak: getaddrinfo is not freed using freeaddrinfo

[Val-de-mar]

There appears to be a memory leak in the file template_cpp/src/include/parser.hpp. The function getaddrinfo is called at line 65, but its result is not properly freed using freeaddrinfo. According to the POSIX documentation, any memory allocated by getaddrinfo must be released with freeaddrinfo to prevent memory leaks.
I hope this feedback is helpful for improvement.
