Description:
------------
Uncatchable fatal error for function call on non-object

Reproduce code:
---------------
...
LPSTR eval_code = "?> $NOVAR->ABC();";
...
zend_first_try {
  if ( zend_eval_string(eval_code, NULL, eval_name TSRMLS_CC) == SUCCESS ) {
...
  }
}
zend_catch
{
} zend_end_try();

Expected result:
----------------
zend_eval_string should throw a fatal error and jump to zend_catch. Fatal error "Call to a member function ABC() on a non-object" is expected to be catchable.

It is working in 5.2.1/Apache2 but no longer in 5.3/Apache2.2

Actual result:
--------------
zend_catch never reached

After reworking my code, I got it working. I cannot detect any reasonable changes other than I use "zend_try" now instead of "zend_first_try".

Btw, I am using output buffering and zend_try together. Making sure, the buffer will close in any cases is nessarry for correct output via webservers.
