There may be an Xlib bug here, but your test program is wrong, so I'm not
convinced. You can't send a request without using one of the GetReq family of
macros in Xlib. When I fix your test program to use GetReq instead of _XSend,
it completes successfully.

Your IO error did not occur in _XSend; it occurred in _XReply, because you
didn't send a valid request, so we couldn't find the reply to return. XCB is a
bit stricter about correctness here than Xlib is, but I've never seen real code
get this wrong.
