Description:
------------
1. Install a recent version of SugarCRM (tried 6.5.16 => 6.5.20)
2. Log in
3. Segfault in clean_non_persistent_constants()

Tested with git head as of 2015-01-14 and 2015-01-20

Test script:
---------------
https://github.com/hhvm/oss-performance

Run:

  hhvm perf.php --sugarcrm-home-page --php5=/path/to/php7/bin/php-cgi

(The script itself is written in Hack, so requires HHVM)

Expected result:
----------------
No segfault

Actual result:
--------------
Program received signal SIGSEGV, Segmentation fault.
