If you visit the file appended at the end of this bug report with
hilit19 enabled, and you enter hide-ifdef-mode and hide-ifdefs, then
^L to re-highlight, you get an error from search.c:

  error ("Stack overflow in regexp matcher");

This is presumably because the many regexps in hilit19 are interacting
badly with the regexp matcher when selective-display is on (in
^M-mode); I'd guess the regexp matcher thinks it's matching one long
line.

Don't have a fix for this one, sorry.  Possibly the regex code has to
know about selective-display (to use ^M as a newline)???
