[support] Drupal 7 PHP and Apache Crash when adding Theme

[Andrew Manson]

Hi All,

I've just come across a problem with my Drupal 7 installation when 
trying to add a new Theme (Zen) using the "+ Install new theme" feature 
as part of the Appearance admin configuration.

My System:
- CentOS 5.5
- PHP 5.2.10 (installed from CentOS testing)
- Apache 2.2.3

Just in case I can't quite explain myself fully on how to recreate it 
here is a demo: http://www.youtube.com/watch?v=K78koI0ovJ4

How to recreate:
* Open the appearance tab in the Drupal 7 administration
* click "+ Install new theme"
* Paste the url of the Zen theme into the text box (this bug also 
happens if you upload the package using the "choose file" option)
* Click "Install" and you will be presented with the authorize.php 
screen prompting you for your ftp login and password
* click "Continue"

Then you will get an empty response.

Checking in the apache logs I get a line like the following:
[Thu Nov 18 15:52:07 2010] [notice] child pid 7412 exit signal 
Segmentation fault (11)

As one of my colleagues suggested I then ran apache in gdb so that we 
could get a backtrace and see what the problem is. We ran:

gdb --args httpd -X 2>&1 | tee gdb-httpd.txt

the gdb-httpd.txt file has been attached. the only things that I did 
were to run the program and then when it crashed i ran "bt full" and 
then just "bt", the output of the latter is included below. You will see 
that the error is caused by the internal php function 
zif_call_user_func_array and it may not be relevant but we notice that 
the "this_ptr" is set to null which might be what is causing the problem.

If someone could please let me know what the best way to resolve this 
issue is that would be very helpful. Also if you would like to request 
any further information please let me know what to do and I will 
cooperate fully to try and get this issue resolved.

Kind Regards,
