cURL: [P]roblem (2) in the Chunked-Encoded data

Question

I have a PHP application that uses Guzzle to make HTTP requests.

I'm getting the following exception:

[curl] 56: Problem (2) in the Chunked-Encoded data [url] http://...

It looks like the problem is with cURL. I've tried to compile latest version of cURL from source, but it looks like it doesn't help.

What could be the problem and how do I fix it?

$ curl --version
curl 7.41.0 (i686-pc-linux-gnu) libcurl/7.35.0 OpenSSL/1.0.1f zlib/1.2.8 libidn/1.28 librtmp/2.3
Protocols: dict file ftp ftps gopher http https imap imaps ldap ldaps pop3 pop3s rtmp rtsp smtp smtps telnet tftp

$ composer show -i

Same problem, solved by upgrade to curl to 7.36 (for some reason apt-get install didn't update as of 14 Aug 2015)

$ sudo add-apt-repository ppa:costamagnagianfranco/ettercap-stable-backports
$ sudo apt-get update
$ sudo apt-get install curl

Curl 6+ solution

(new Client)->post(http://post.com, [
    'multipart' => $post,
    'curl'        => [
        CURLOPT_HTTP_VERSION => CURL_HTTP_VERSION_1_0,
    ],
]);

Basically force http 1.0 because reasons.

I had a similir probem and solved it by using http/1.0 it is a very weird thing but it looks like something is wrong in the libcurl or the curl php module and guzzle fails in the post-process of the response.

I wrote a post here describing the thing

This sounds earliy familiar to the issues mentioned by Michael Dowling (Guzzle creator) on his blog about Chunked Transfer Encoding in PHP with Guzzle.

To answer the question of "how do I fix it" your options could be either:

modify the settings of the web service (may or may not be feasible); and/or
modify your request object.

Without code displaying how your client and request objects or your curl "call" I would simply be speculating.
