I'm having a problem that I believe is a side-effect of this issue.

I'm using the Twig extension in a project, and it uses the IteratorAggregate interface.

When the locale is tr_TR, I get
  Fatal error: Interface 'IteratorAggregate' not found in ..

When I do setlocale('en_US.UTF-8') or 'es_ES.UTF-8', everything works fine.

I can provide the PHP compilation command line but the IteratorAggregate interface is built-in, so I
assume it would be practically impossible to remove the interface during the compilation process.

Hi this bug is still exists in new php versions. We have same problem with php version 5.6.18 and
from your comments should be fixed in 5.5 but it isn't. Question is why change locale is
affecting interpreter matching method which should be independend from locale. And stable in any
case. So some one can tell me when this problem will be solved because for multi language solution
using locale as language settings and in some cases use the data formatting unique by country. Or
maybe you can provide some information how to omit that error or some fix for that (maybe patch)

So, to sum things up :
The bugs has only been fixed in 5.5 branch. It mainly uses a char map to lower 
characters instead of relying on locale-aware (possibly buggy versions) system's 
libc.

You can find details with internal zend functions affected directly by reading 
the source, here : http://lxr.php.net/xref/PHP_TRUNK/Zend/zend_operators.c#45

It looks like snaps is serving 5.4 under the name of php-trunk. Not sure why. 
Could you submid a website bug for that and send me the bug ID?
In the meantime you could use github: https://github.com/php/php-src just use the 
"zip file" option and you could build it from there.

thanks for the response.

$ wget http://snaps.php.net/php-trunk-201209131330.tar.gz
$ wget http://snaps.php.net/php-trunk-201209131330.tar.bz2
$ wget http://snaps.php.net/php-trunk-201209131330.tar.xz

$ for type in gz bz2 xz; do mkdir $type; (cd $type; tar -xf ../php-trunk-201209131330.tar.$type);
done

$ grep "PHP_VERSION " {bz2,gz,xz}/php-trunk-201209131330/main/php_version.h
bz2/php-trunk-201209131330/main/php_version.h:#define PHP_VERSION "5.4.8-dev"
gz/php-trunk-201209131330/main/php_version.h:#define PHP_VERSION "5.4.8-dev"
xz/php-trunk-201209131330/main/php_version.h:#define PHP_VERSION "5.4.8-dev"

is that ok for trunk snapshots then ?

You should be using 5.5 (or master) branch of PHP. It is not fixed in 5.4 due to necessities of
binary APIs change which is not possible in stable version. Trunk does not announce itself as 5.4
but as 5.5, so there must be some mistake. 

However if you feel very adventurous, you can take 5.5 commit (it's marked with the bug #) and
cherry-pick it into your 5.4 branch.
