This plain tex document demonstrates \pdflastmatch failing if used after
a \pdfmatch that returned no matches.


segfaults  (for me on cygwin tl2016 pretest) and originally reported by
Henri Menke in stackexchange chat on Debian linux TL 2015.

he commented

> Ohhhh. Could also be a libc bug. Because it works in GDB.
