Bug description:Recursion detection broken when printing GLOBALS

Description:
------------
I found this while going through
https://3v4l.org/bughunt/7.3.0/7.2.13+7.2.12.
Previously when printing
_GLOBALS - recursion was detected and prevented. This seems broken

Test script:
---------------
See https://3v4l.org/AdLgJ

print_r($GLOBALS);

Expected result:
----------------
Array ( ... ) [GLOBALS] => Array *RECURSION* )

Actual result:
--------------
Fatal error: Allowed memory size of 67108864 bytes exhausted (tried to
allocate 31461376 bytes) in /in/AdLgJ on line 3

Process exited with code 255.
