Unfortunately the version of libxml2 that pg is using on that system is
in fact 2.9.4, not 2.9.8:
root(at)capybara:~# ldd /usr/lib/postgresql/10/bin/postgres | fgrep xml
libxml2.so.2 => /usr/lib/x86_64-linux-gnu/libxml2.so.2 (0x00007f332517f000)
ii libxml2:amd64 2.9.4+dfsg1-6.1ubu amd64 GNOME XML library
and poking at it with gdb shows exactly the same bug that I found on my
system, though on yours it fails at a somewhat different place (when
trying to print the file context as part of the error message, but the
basic problem is still that input->cur is off in the weeds).
