I want to base64-encode a username and password (i.e. I want it as a
string), and I thought it would be cool to do that with CF functions
(so I don't have to write the whole base64 stuff, or download some
hacked-together library for that).

I create a CFHTTPMessageRef with ...CreateResponse(..., 401,...).  I
set its header field to the usual WWW-authenticate record; I set its
body to an NSData from an empty string.

I do the same to create a request (with a random URL).

When I call CFHTTPMessageAddAuthentication(request, response, myUser,
myPass, kCFHTTPAuthenticationSchemeBasic, FALSE), I get a crash.
(afterwards, I would have extracted the header value to get my string)

Does anybody have an idea why?  After all, I created nice, clean
HTTPMessage objects with Apple's own functions, and I even set all
their values...
