Server issue Error on new user moderation page with PHP 5.5.1

This is occurring with enableListeners set to false too, and definitely was not happening before on PHP 5.4.17

(XF 1.2.0)

I worked this out to be an incompatibility with some of the optimizer settings in Zend Optimizer+. The built in opcode cache in 5.5 is based on this, though I didn't think it had the optimization options.

There's not a lot that we can do as it simply seems to make the code execute differently than as defined. The only workaround I found was to turn off the optimization levels.

On closer inspection it seems I can't access the admin CP at all (same error)

Is there a workaround other than disabling the opcache extension? It's running on basically all default settings

I'm surprised other people haven't run into it (and that I didn't for example, in my tests) if it's a general issue.

Try setting opcache.optimization_level to 0.

Seems the cause is a conflict between DBG and the opcache extension - disabling DBG fixed it

Just checked my Ubuntu server at home, and by default it's commented out

; A bitmask, where each bit enables or disables the appropriate OPcache
; passes
;opcache.optimization_level=0xffffffff

Using debian Wheezy with dotdeb php5.5 packages here and I found removing php5-xdebug fixed the problem immediately.

Try setting opcache.optimization_level to 0.

Just FYI - this worked for me.

Just had a fresh install and ran into this problem. Using 5.4.19. Commenting out zend_extension="ext/php_opcache.dll" solved my problem (I don't need it on my dev server anyways)
