ID: 51357
Updated by: johan...@php.net
Reported by: pesu at obsidian dot cz
Summary: httpd crashes with segfault signal 11
-Status: Open
+Status: Bogus
Type: Bug
Package: Apache2 related
Operating System: CentOS 4.8
PHP Version: 5.2.13
New Comment:
Do not file bugs when you have Zend extensions (zend_extension=)
loaded. Examples are Zend Optimizer, Zend Debugger, Turck MM Cache,
APC, Xdebug and ionCube loader. These extensions often modify engine
behavior which is not related to PHP itself.
In the stacktrace you can see "Non-static method %s::%s() %s be called
statically" so the code is doing something wrong.
Other than that: We can support neither Zend's modifications nor unknown
PHP applications.

I find out, that problem starts when using ZendEncoded file (with
ZendOptimizer 3.3.9 x86_64). Because php file is encoded, I have no
human readable example script, but I have following bt:

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 the script requires a
database to demonstrate the issue, please make sure it creates
all necessary tables, stored procedures etc.
Please avoid embedding huge scripts into the report.
And please also add the full stacktrace, the two frames say nothing
useful.
