Very long URL returning CURLE_URL_MALFORMAT

I'm having trouble figuring out what I'm doing wrong with an
implementation of libcurl that is working for everything else I can
throw at it. I've done a lot of searching stack overflow, etc and
haven't figured out the issue yet.
Using the latest libcurl I'm getting the above error back immediately
with no data sent. It looks fine as far as I can tell and if I put the
same URL into command line curl it works fine.

It's a GET so I'm just using this to set it up:

curl_easy_setopt(m_cURLFile->handle.curl, CURLOPT_URL,
JRStringUTF8(m_fnURL.GetFilename()).GetString());

The JRStringUTF8(m_fnURL.GetFilename()).GetString() returns a pointer to
the null terminated c string exactly as seen above.
All of the rest of the curl setup is precisely how I'm doing it for
every other GET request.

I run it through URL validators and it's fine.
Is there some sort of maximum URL length?

TIA,
Bob
