I set up a clean install of TT-RSS, using MySQL for DB, and the only other change to the config.php file is pointing it to /usr/bin/hhvm instead of /usr/bin/php.

Upon loading the index page, I get a lot of "HipHop Notice: Undefined index" errors, but it seems to work ok. Entering the wrong credentials properly throws an error on the web-page, etc.

If I enter the correct credentials I immediate get: "[hphp] [2490:50c1d700:3:000203] [7fb1654a34a0:9e4c1a:9e4d09:9c4f73:9c6ea1:9d9d1a:a83f66:a84a3e:ec5806:a78f2d:e333d7:e33590:7fb166be4e9a:7fb165560ccd] Core dumped: Segmentation fault"

This is on a vanilla install of Ubuntu 12.04 64-bit with the latest updates and patches, mysql, and HHVM 2.1.0 from the deb.

Hi @epyonavenger, can you try to reproduce with a debug build of HHVM and provide more information? Thanks for reporting this.

Do I need to build that from source, or is there a debug deb out and about somewhere?

I don't know of any packages, unfortunately.

Ok! I will try to get it compiled for debug and then re-run the old fashioned way.

Thanks. If you want to take a look at the core and try to identify the problem, that would help (we'll be happy to take a pull request), otherwise we'll look at this at some point in the future.

In the meantime, if you have a small PHP sample from TT-RSS that causes us to emit the "Undefined index" notice that does not result in any notice/warning output in Zend, that would be helpful as well, it might be related.

Apologies if it is a dumb question, but how would be the best method to get you a sample? TT-RSS has all their source posted here: https://github.com/gothfox/Tiny-Tiny-RSS and I just did the most basic install possible. That said, I can definitely mess around with it to try and get you more info, I'm just not sure where to start.

What would be helpful is a single standalone PHP file that reproduces 'Undefined index' issues in HHVM but does not produce any issues in Zend -- this would be an isolated repro of that issue. Does that make sense?

Just a short ping to let you know, that this seems to be fixed in current daily. At least it is working for me with apache2 in Ubuntu 14.04.
