Judging by the timestamps and our inability to reproduce it, I have to
assume that the SIGTERM was sent to mocp by the user who posted the log.

We've never compiled curl against c-ares; though for the sake of being
thorough, I tested with curl linked against c-ares (1.7.4) and mocp
streams properly.

Here's the build options that I that can reproduce success with:

  --random=/dev/urandom
  --prefix=/usr
  --mandir=/usr/share/man
  --disable-dependency-tracking
  --enable-ipv6
  --disable-ldaps
  --disable-ldap
  --enable-manual
  --enable-versioned-symbols
  --with-ca-path=/etc/ssl/certs
  --enable-threaded-resolver
  --without-libidn

The broken mocp behavior is exhibited solely with the addition of
--enable-threaded-resolver.
