may have broken git behind a firewall:

https://bugzilla.redhat.com/show_bug.cgi?id=2013288

I am behind a firewall and using gitproxy:

exec socat - socks4:proxy-server-name:$1:$2

I got

$ git clone git://gcc.gnu.org/git/gcc.git
Cloning into 'gcc'...
fetch-pack: unexpected disconnect while reading sideband packet
fatal: early EOF
fatal: fetch-pack: invalid index-pack output
$

Both

$ git clone --depth 1 git://gcc.gnu.org/git/gcc.git

and

$ git clone https://gcc.gnu.org/git/gcc.git

work.

$ git -c protocol.version=1 clone git://gcc.gnu.org/git/gcc.git

also works.

It's not the firewall; it's socat not handling half-duplex shutdown very
well (though you are right that it is related to the commit you found;
that's when Git started closing the write pipe when it's done writing).

More discussion in this thread:

(the short answer is: use "socat -t 10").

-Peff

Yes, "socat -t 10" works.
