Operating system: GNU/Linux 2.4.20
PHP version:      4.3.3
PHP Bug Type:     Reproducible crash
Bug description:  Crash / "String is not zero-terminated"

Description:
------------
I run a rather large PHP System (250k+ LOC).
Recently, a number of "Segmentation-Faults" started popping up
in my Apache error log. Only some of the PHP pages caused a segfault.
These segfaults are mostly reproducible, but could be suppressed by moving
code around - like changing order of method definitions, etc.

So i set up an identical system as our production server, but with
--enable debug. The segfaults did not happen anymore, but i keep getting
notices like these:

[21-Sep-2003 16:25:34] PHP Warning:  String is not zero-terminated
(SetVerband̏**rtID'  aa) (source:
/home/develop/mod_php-4.3.3/Zend/zend_opcode.c:165) in Unknown on line 0

The problem occurres with PHP from at least 4.2.2 to 4.3.3, regardless
wether running with Apache 1.3x or Apache 2.0.

I would like to provide more information, but i don't know how .. any info
on how to trace the reason for this problem would greatly appreciated.


Reproduce code:
---------------
sorry, i'cant construct a small snippted reproducing this error - it seems
to pop up on pages with a large amount of used objects, though (but thats
only a guess ..)

Expected result:
----------------
well, no php crash?
