The sockaddr union struct must be zero-out before usage at least for IPv6. IEEE Std 1003.1, 2004 Edition says: --- The sockaddr_in6 structure shall be set to zero by an application prior to using it, since implementations are free to have additional, implementation-defined fields in sockaddr_in6.

It was reported that fcgiwrap doesn't work with IPv6, I start testing and found that the following command fails :
After investigations I found that the issue was caused by an uninitialized sockaddr structure which is mandatory for IPv6. After that, fcgiwrap binds on IPv6 addresses without issue.
