I've tried the combination of

  ca14dd1d4628094dd33d5d94694dcf5f29e843b8
  7dab3ee7ab54b3c2e7bc24170376054786c01d6f

and this patch against Debian's current source package.

Emacs no longer hangs, but I get incorrect highlighting,
for instance on the following XML file.

<root>
<!-- comment -->
<a>"a'</a>
<!-- comment -->
</root>

Highlighting starts to be wrong at the single-quote character.
I've attached a screenshot obtained with the -Q option.

Did I miss anything?
