Topic: [Solved] 5.6.5 gd fails; undefined symbol: gdVersionString
Attempted to upgrade to 5.6.5-1 earlier today on CentOS 6 and gd wouldn't work...
PHP Warning: PHP Startup: Unable to load dynamic library '/usr/lib64/php/modules/gd.so' - /usr/lib64/php/modules/gd.so: undefined symbol: gdVersionString in Unknown on line 0
Downgrading to 5.6.4-2 resolves the issue. One tier of our app servers consistently exhibit this issue, though another box I tried it on had no problem with the install/upgrade.
Here's what's on deck when I yum upgrade php/*:

Phalcon 1.3.4 (from source) is installed on both systems, but it's also installed on the system that doesn't have any issues with including gd.
Any way to fix this? Any more info that would be helpful in finding out what's wrong? I can compile gd if I have to but I'd rather not (and I'd rather not stay at 5.6.4).
