Cannot get a backtrace from the instructions on bug submission. The PHP
session does not actually crash, generating a core dump, but exits with
a fatal error. The text of the error is gibberish, but nevertheless it
does not die.

How can we stop or investigate the process at the point of the error.

It looks like PHP's symbol table gets corrupted during an earler part
of the code. Is there anyway we can investigate this further.

yours, Marcus.

This is the bug from hell.

It is random crashing in a section of our unit tests. On Windows the
crash manifests itself as...

The instruction "(1)" referenced memory at "(2)" which is not writable
where (1) is :0x77fcb9b1 (once), 0x77fcb892 (twice), 0x77fcb9fb (once)
on a random attempt of two dozen tries.

There is too much code to post here and we cannot yet isolate it - our
individual unit tests all pass. We are working on a backtrace from a
Linux machine and will add to this bug soon.

The code that was changed that started generating these problems was
mysql related. There are a lot of references in that code (it is a
persistent object library).

The problem manifests itself in Linux with random fatal errors such as
unknown function where the function name is simply "<()" !? It also
happens both with version 3 and 4 of  MySQL and versions 4.2.3 and
4.3.0 of PHP.

It is a complete show stopper.

yours, Marcus.
