Thanks, Anatol, for the quick reply. I've already committed tests
for four closely related bug reports (actually, they're duplicates)
to my sxe-var-dump branch[1]. However, I've noticed that bug #68946
and bug #67572, which I deemed related to this one, won't be fixed
with the given patch. I'll investigate.
With regard to older libxml versions: it seems very reasonable to
test with these. I'll see if I can build the mentionend versions
of libxml2 on Windows (some preliminary tests were successful).

Hi Christoph,
thanks for following on this. I don't have all the details in my head, however you go into the
same direction. Whether the check you've found works better only the tests can decide, i'd
say. If it is - so lets take it.
One note though. The trickiness of this ticket is - we deal not only with PHP itself actually, but
with the behavior change in libxml and the previous fix might have been not 100% sufficient.
IMHO what should be done - we should ensure that this fix doesn't break things when PHP is
linked with 2.7.x to 2.9.x. Probably the easiest done on Linux when fetching particular libxml
version, installing into some prefix and compiling PHP with it.
Are you in the mood to do this? If it's ok under say PHP-5.5 and libxml 2.7.7 2.7.8 2.8.0 2.9.1
2.9.2 - then please create a PR with all the aggregated tests from the tickets you've found
related and ping me so i'll test it as well. Does it sound eligible to you?
Thanks.

The following patch has been added/updated:
Patch Name: sxe-var-dump

Re-opened because of evgeniy's comment. This bug seems to be
closely related to bug #62639.
Adding the check for !node->next in the commit apparently only
solves some issues. It seems to me that instead it has to be
checked for sxe->iter.type, because when this is SXE_ITER_NONE it
doesn't make sense to execute the else clause.
With the attached patch sxe-var-dump.patch all ext/simplexml/tests
run fine, as well as the test script of bug #69491.
Anantol, can you please have a look at the issue. If useful, I can
make a pull request with some further tests regarding whitespace
issues.
