FYI, this problem only occurs with mingw version.

Perhaps it is getting confused between ipv6 and 4? (after compiling with -g3

(gdb) print *addr
$6 = {sin6_family = -1912, sin6_port = 34, sin6_flowinfo = 1851828526, sin6_addr = {_S6_un = {_S6_u8 = "╕{>\000╨Y\236\000p¿`n\002\000\000", _S6_u16 = {31672, 62, 22992, 158,

Just as a note, this still occurs (I think only with GCC 3.4.5 mingw)

I can't reproduce it on Windows Vista at all.
What's your platform, and the version of winsock2?

It's 6.0.6001.18000 on Vista.

I'll try it on XP, if possible, later.
