Comment 21 for bug 1690485

I lied. I experimented with ./configure flags.

    --with-kerberos5=/usr

is definitely the flag that is triggering the crash. Removing this
flag alone cures the crash.

Command that was used:

../configure --build=x86_64-linux-gnu --prefix=/usr \
      --includedir=\${prefix}/include --mandir=\${prefix}/share/man \
      --infodir=\${prefix}/share/info --sysconfdir=/etc \
      --localstatedir=/var --disable-silent-rules \
      --libdir=\${prefix}/lib/x86_64-linux-gnu \
      --libexecdir=\${prefix}/lib/x86_64-linux-gnu \
      --disable-maintainer-mode --disable-dependency-tracking \
      --sysconfdir=/etc/ssh --libexecdir=\${prefix}/lib/openssh \
      --disable-strip --with-mantype=doc --with-4in6 \
      --with-privsep-path=/run/sshd --with-pid-dir=/run \
      --with-tcp-wrappers --with-pam --with-libedit \
      --with-systemd \
      --with-xauth=/usr/bin/xauth \
      --with-default-path=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games \
      --with-superuser-path=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin \
      --with-cflags="-Wdate-time -D_FORTIFY_SOURCE=2 -g -O2 -fdebug-prefix-map=/home/kennykb/debian.org/openssh=. -fstack-protector-strong -Wformat -Werror=format-security -DSSH_EXTRAVERSION=\\\"Ubuntu-3\\\"" "--with-ldflags=-Wl,--as-needed -Wl,-Bsymbolic-functions -Wl,-z,relro -Wl,-z,now" \
