libcurl putting empty file on Mac OS X

Hi,
I have some simple code (included below, and the same thing happens
with the httpput example) that tries to put a file onto a Windows
machine that I have running with Apache and WebDAV. This code works
just fine on Linux, and when I do a curl -T from my Mac, I can put the
file up there. However, when I run this code on my Mac, Apache's
access log says:

"PUT /test.mov HTTP/1.1" 201 268
"" 501 298

and there's an empty file on the server. I'm not sure where the extra
command is from. Running curl with --trace gives me:

== Info: About to connect() to IP_ADDRESS_HIDDEN:80
== Info: Connected to IP_ADDRESS_HIDDEN (IP_ADDRESS_HIDDEN) port 80
=> Send header, 247 bytes (0xf7)
0000: PUT /test.mov HTTP/1.1

008a: Pragma: no-cache
009c: Accept: image/gif, image/x-xbitmap, image/jpeg, image/pjpeg, */*
00de: Content-Length: 13131

and the output from the included program is:

Any ideas are appreciated!
