Description:
------------
Under phpdbg 7.2.20 include unexistent file results to fatal error/memory exhausted.
Under phpdbg 7.2.19 include unexistent file works as expected.

Test script:
---------------
echo '<?php include "unexistent";' | docker run -i php:7.2.20 phpdbg -qrr -s
''
[PHP Warning:  include(unexistent): failed to open stream: No such file or directory in Standard
input code on line 1]
[PHP Warning:  include(): Failed opening 'unexistent' for inclusion
(include_path='.:/usr/local/lib/php') in Standard input code on line 1]
[PHP Fatal error:  Allowed memory size of 134217728 bytes exhausted (tried to allocate
2305843009750564865 bytes) in Standard input code on line 1]

echo '<?php include "unexistent";' | docker run -i php:7.2.19 phpdbg -qrr -s
''
[PHP Warning:  include(unexistent): failed to open stream: No such file or directory in Standard
input code on line 1]
[PHP Warning:  include(): Failed opening 'unexistent' for inclusion
(include_path='.:/usr/local/lib/php') in Standard input code on line 1]

Expected result:
----------------
Just two warnings.

Actual result:
--------------
Two warnings and fatal about memory.
