Bug 278814 – dev-lang/php-5.2.10 does not work with dev-php5/ZendOptimizer-3.3.3-r1

• Product: Gentoo Linux
• Status: RESOLVED TEST-REQUEST

[Description Stuart Shelton 2009-07-23 09:33:29 UTC]

We have to make use of a closed-source PHP webapp named Helpspot which is obfuscated with ZendOptimizer.  With php-5.2.10 the execution from CRON of scheduled tasks to read emails into the webapps database segfaults reliably, whereas with php-5.2.9-r2 and prior this has always worked. With the latest ebuild, php isn't just erroring out, but is actually segfaulting - indicating an underlying problem with php (or Zend) rather than with the code being executed.

ZendOptimizer is still at version 3.3.3-r1 (although I did rebuild it against the latest PHP), so there may potentially be a conflict between this and the latest PHP.  Having said this, the main webapp (which also requires Zend but runs via (Fast)CGI) still works perfectly with 5.2.10 - it is only the two scheduled tasks from CRON (run via php-cli) which fail.

I've also tried reinstalling and reverting MySQL, just in case the recent 5.0.70 update caused problems - it had no bearing.

This problem is reproducible on multiple x86 and AMD64 servers.

With php-5.2.10 temporarily unmasked, the USE flags are:

$ emerge -pv php

I realise that this is all rather vague - but if anyone else has problems with webapps requiring Zend or with php-5.2.10 in general, at least registering this problem might help...

According to the vendor:

"Yes, there Zend has a known issue with Zend Optimizer 5.2.10 and 5.3 so you should roll back to 5.2.9 until Zend has released an updated optimizer. We've been in touch with Zend and are pushing them as hard as possible to get this new  Zend Optimizer out as fast as possible."

I guess that's not enough to warranty putting a block on the 5.2.10 ebuild, but I guess that there should at least be a large ewarning that ZendOptimizer may not work with it.

[Comment 3 Matti Bickel (RETIRED) 2010-04-12 19:00:26 UTC]

Hi, I'm sorry this bug has not gotten a quicker response.

With some time passed, there's now ZendOptimizer-3.3.9 and php-5.2.13 in the tree. Does the segfault still happen with those two?

Zend claims compatibility with any minor version of php 5.2, so you should be fine. If not, please reopen this bug.

[Comment 4 Stuart Shelton 2010-04-13 14:10:47 UTC]

Confirmed fixed - php-5.2.13 works correctly with ZendOptimizer-3.3.9.
