1. Starting from `emacs -Q'
2. open a xml file with contents shown below:
<?xml version="1.0" encoding="UTF-8"?>
<window>
<control>
<!--<visible>Player.HasAudio + !Skin.HasSetting(homepageMusicinfo)</visible>-->
<visible>false</visible>
</control>
</window>
3. Turn on flyspell mode with `M-x flyspell-mode'
4. Move the cursor to the comment start '<!--', then begin to delete
comment start chars with C-d. When the line changes to :
<visible>Player.HasAudio + !Skin.HasSetting(homepageMusicinfo)</visible>-->

Hi,
Cannot reproduce here with emacs-snapshot 20140101 in Debian,
[GNU Emacs 24.3.50.1 (x86_64-pc-linux-gnu, GTK+ Version 3.8.6)].
Here aspell is used spellchecker [/usr/bin/aspell::default] and LANG was set
to "es_ES.UTF-8". Same with
$ LC_ALL=C LANG=C emacs-snapshot -Q test-16449.xml
$ LC_ALL=C LANG=en_US.UTF-8 emacs-snapshot -Q test-16449.xml
aspell-es and aspell-en are installed. Which spellchecker and dictionary are
the default at your site? Is something relevant in your messages buffer?
Regards,
--

Reproduced. Consider simpler example with the following XML:
<?xml version="1.0" encoding="UTF-8"?>
<tag0>
<!--<tag1>Text</tag1>-->
</tag0>
Visit this file in nxml-mode and try to eval:
(goto-char (nxml-token-after))
from the beginning - you should advance token by token after
each evaluation, up to the end of buffer.
Next, remove comment, i.e. change the XML above to:
<?xml version="1.0" encoding="UTF-8"?>
<tag0>
<tag1>Text</tag1>
</tag0>
Then try to advance from the beginning again. In my test, nxml-token-after
stops at '<' of '<tag1>' and never continues. Due to this, there is an
endless loop in nxml-forward-single-balanced-item (lisp/nxml/nxml-mode.el):
1627 (defun nxml-forward-single-balanced-item ()
1628 (condition-case err
1629 (goto-char (let ((end (nxml-token-after)))
1630 (save-excursion
1631 (while (eq xmltok-type 'space) ; this is an
1632 (goto-char end) ; endless
1633 (setq end (nxml-token-after))) ; loop
BTW, I have no ideas why C-g doesn't help.
Dmitry

Here is the xbacktrace after the hang:
(gdb) xbacktrace
"xmltok-forward" (0xffff93d0)
"nxml-token-after" (0xffff9908)
0x1255860 PVEC_COMPILED

Turn off flyspell-mode and everything is fine.
