Thanks for a thorough bug report. I looked through your strace output,
and this really does look like another case of OpenSSL getting SIGPIPE
while closing the connection.

It's odd, though, as your curl version has my patches, along with
similar extra fixes in 854aca5 (multi: ignore sigpipe internally,
2014-02-17). But I guess there may be a code path that needs similar
treatment.

The easiest way to find it is probably to attach a debugger to the
running git-remote-https, and get a backtrace when it dies from SIGPIPE.
You'll probably want to install your system's debug packages for curl,
too.

I have curl version 7.36 though, in case some of the other output matters:

[normal@laptop tmp]$ curl --version
curl 7.36.0 (x86_64-unknown-linux-gnu) libcurl/7.36.0 OpenSSL/1.0.1g
zlib/1.2.8 libssh2/1.4.3

Another possibility is that your curl binary is up-to-date, but you are
linking against an older version of libcurl that does not have the
SIGPIPE workarounds.

I'm not sure of the best way to check that, but a hacky way under Linux
is:

  $ ldd $(git --exec-path)/git-remote-https | grep libcurl
          libcurl.so.4 => /usr/lib/x86_64-linux-gnu/libcurl.so.4
  $ strings  /usr/lib/x86_64-linux-gnu/libcurl.so.4 | grep '7\.'
  CLIENT libcurl 7.36.0
