Hi,

Are you saying it doesn't crash without --enable-socks? That option is obsolete,
I wouldn't use it. It only adds -lsocks to the link line, but nothing more
useful than that.

Maybe something wrong with libc, those inputs to strftime look fine to me. I don't
think I can help debug a freebsd/64-bit system.

Regards,
Peter.
