| Doc Text: |
*getaddrinfo* no longer accessing uninitialised data
On systems with the *nscd* daemon enabled, the `getaddrinfo()` function in the *glibc* library could access uninitialized data and consequently could return false address information. This update prevents uninitialized data access and ensures that correct addresses are returned.
