Hello,

Please look at the test code found at http://pastebin.org/167215
it's a small program that attempts to post some data to a website and
immediatly aborts the upload by returning a non-zero value from the
progress callback.

I'm noticing a different behaviour between the curl library installed
in my system (curl-7.19.7) and the latest version (curl-7.20.1):

(recompiled and using curl 7.20.1 now)

% LD_LIBRARY_PATH=`pwd`/lib ./test
libcurl returned: Couldn't connect to server

Can anyone tell me why with the new library the returned error code is
"Couldn't connect to server" (which seems wrong to me imo)? Is this
expected behaviour?

Thanks!
