Description of problem:

In version from upstream, squid 3.3.8 has a bug which keeps crashing the proxy server.

2016/07/25 11:56:36| assertion failed: Server.cc:246: "r->body_pipe != NULL" 2016/07/25 11:56:40| Starting Squid Cache version 3.3.8 for x86_64-redhat-linux-gnu...

Version-Release number of selected component (if applicable):

3.3.8

How reproducible: Always

Steps to Reproduce:
1. generate empty file ( e.g. : > empty.txt)
2. export ftp_proxy=http://<yourproxy>:3128
3. lftp -c 'open <yourftphost>; put empty.txt'

Actual results: Squid server crashes and restart. Your lftp client willl try to do the same in 30 seconds... so it will keep crashing your server until yo do something.


Expected results: Create an empty file in the ftp server, and the squid server keeps working.

BTW, this problem happens also in squid 3.1.23 in RHEL 6. We ended updating our servers to 7 hoping the new version will address this problem, without success.
