I'm unable to produce a simple test case, because the bug only appears
with the right combination of database calls and when all the classes
in our application are include()'d (I'm guessing about 100+ classes are
in use, spread over ~500 files). Unfortunately, I'm not at liberty to
provide the source code.
I understand this complicates debugging a lot, but I can run GDB traces
and compile debug versions of PHP with any patches/changes you might
suggest, or anything else you might want, and post back the results.
Hope to hear from you soon!

Thank you for this bug report. To properly diagnose the problem, we
need a short but complete example script to be able to reproduce
this bug ourselves.
A proper reproducing script starts with <?php and ends with ?>,
is max. 10-20 lines long and does not require any external
resources such as databases, etc.
If possible, make the script source available online and provide
an URL to it here. Try to avoid embedding huge scripts into the report.

Please don't put such huge backtraces in the bug report, instead, put
them online somewhere and paste the URL here.
I deleted the one huge comment of yours, it can be viewed still in the
mailing list archives, so don't readd it here..

OK, I grabbed the http://snaps.php.net/php5-latest.tar.gz file and
compiled, changed all 'php4' references to 'php5' in httpd.conf and
started up apache in gdb again.
With this version of PHP, our application won't run at all. I get an
error "Cannot reassign $this in XXX on line YYY ". The source code
referred from that error message looks like this (in the middle of a
class)
function printHtml() {
$asw =& $this; <- line with error
..
}
This occured in three different files. By changing all places into
"$asw = $this" (no '&'), I got things running fine. (Isn't assignment
of objects by-ref by default in php5 anyway?)
My code seems to work fine in both the PHP5 snapshot of today, and in
PHP-5.0.3. (I didn't have to remove the '&' to get things to run in
PHP-5.0.3).
I guess this means this is a php4 only bug (either that, or php5 is
different enough so that the bug is not visible in this particular
case).
What's the next step? :)
