I note that the release notes say "However, there still remain a few
outstanding problems with fontlock that must be fixed before we retire
21.1", but I can't find any description of these problems by searching
the archive -- have I hit them, or is this something else?
Thanks

No, the "problems with fontlock" are that it's slow. I have no idea
what's going on with this.

Posting to c.e.x is the second-worst way to get a bug fixed (the worst
being not to post at all). None of the Windows core developers hang
out there.
Please post a backtrace using M-x report-emacs-bug. If you don't use
XEmacs as your MUA, save the resulting buffer to a file and attach it.

Thanks for telling me how to get this in front of the right people!

This bug report will be sent to the XEmacs Development Team,
not to your local site managers!!
Please write in English, because the XEmacs maintainers do not have
translators to read other languages for them.
Please describe as succinctly as possible:
- What happened.
- What you thought should have happened.
- Precisely what you were doing at the time.
Please also include any C or lisp back-traces that you may have.

Dear Bug Team!
Build: 21.4.8, cygwin (xemacs-i686-pc-cygwin-21.4.8.tar.gz), Windows 2K
Problem: Same as every other build since 21.4.3 (which aborts and survives):
Fatal error (11).
. . .
re-search-forward("--[^-]+\\(-[^-]+\\)*--" 215514 t)
# bind (highlights matcher keyword nkeywords iter old-progress
progress bufname keywords case-fold-search loudly loudvar end start)
font-lock-fontify-keywords-region(1 215514 nil)
. . .
This is the same fault I hit with 21.4.5, .6 and .7
Doesn't happen with 21.4.3.
A more attentive check shows that fontification of the crash-provoking
file under 21.4.3 provokes an abort! Modest work with edebug does not
reveal any way of finding how the abort is being raised. . . ah, if I
edit out the condition-case in font-lock-default-fontify-buffer, I see
File mode specification error: (error "Stack overflow in regexp matcher")
So it seems possible that under 21.4.5 and subsequently, under cygwin, (some)
stack overflows cause a segfault --- does this help localise the
problem?
A file that will provoke the prolbem can be found at:

The font-lock-keywords are coming from psgml-html
