New Comment:
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 avoid embedding huge scripts into the report.

Description:
------------
I've a script that reads and writes several hundred MBs of data from a
mysql database. The data is handled in a number of ways. Crash occurs
at the same spot after a lot of data has been handled. First symptoms
was that a method call on a newly created object suddenly gave a "call
on non-object" error after 70000 iterations in loop, and then
segfaulted. Perplexed, I added an if(is_object( ...)) around the
offending statement, with the result that the crash occured a few lines
down instead. A sign of memory corruption?
Configure string: --with-mysql --with-apxs --with-zlib
Reproduce code:
---------------
The script is part of a larger package of code. Perhaps someone can
look at the backtrace and tell me what to look for, and then I can post
some relevant lines.
Expected result:
----------------
Anything but a segfault.
Actual result:
