I believe that particular effect is an artifact of your debugging and not a
bug in libcurl.

Then I suggest you check what kind of data the server actually returns. If not
with libcurl's HEADER or DEBUGFUNCTION, use a network tool to capture the HTTP
traffic.

And check the server end. What does the server believe it has received and
what has it sent?

AFAIK, there's only one bug in 7.10.5 that can cause error 52 to occur
wrongly, and that only happens if the server returns non-compliant HTTP (which
is fixed in CVS). There might of course be others still unknown to me.
