Description:
------------
PHP doesn't allow to use references in short if construction - I don't have idea 
why it's limited. I think it should be improved in future releases.

Test script:
---------------
$this->_currentExceptionInfo = ((isset($this->_exceptionsMap[$code])) ? &$this->_exceptionsMap[$code] : &$this->_exceptionsMap[self::X_INTERNAL]); //Error

//The same function but it works as expected
if(isset($this->_exceptionsMap[$code])) $this->_currentExceptionInfo = &$this->_exceptionsMap[$code];
else $this->_currentExceptionInfo = &$this->_exceptionsMap[self::X_INTERNAL];

"Short if" is known as ternary operator.

What you want to write is:
$this->_currentExceptionInfo =& ((isset($this->_exceptionsMap[$code])) ? $this-
>_exceptionsMap[$code] : $this->_exceptionsMap[self::X_INTERNAL]);

BTW. Using references is a bad idea.
This request is invalid.

This appears to stem from misunderstanding.
