Closing on reporter's request:
Sorry,
I would have used the bugtracking system, but the "retrieve
password"-function just gave me an empty page this evening...
Currently, I'm no longer involved in the project that gave us this
error. I'm not planning in getting involved again. Please feel free to
close the bug due to inactivity.

Checking if this thing is still alive. Do you get the same problem with
5.3.2?
Thanks!

Well, do you have any tips in what to do with the trace? Sorry, but a
reproducible case would be much more worth than the trace.
Alternatively, is it possible to enable the mysqlnd trace?

Do you have any tips on how to find the respective lines of code in a
70000 lines of code project which eventually cause the crash? All i can
see is the dying apache worker thread and the corresponding message in
the system log. And it is very annoying, that this happens only on the
productive system. No crashes on our development and test machines.
I would gladly provide a test script. Just tell me where to start
digging.

Any chance to provide a test script? I know its hard, but its also hard
to say anything based on the backtrace and without a reproducible test
case.
Thanks,
Ulf

I used the latest Snapshot 5.3.1-dev from Thu Aug 20 15:19:10 2009
The crashes became less frequent. Instead of 10 in 5 Minutes i caught
only 5 in 3.5 hours. But the crashes still occur:
