PHP Bug Type: Reproducible crash
Bug description: sprintf('%s',join('',array(false))); crashes
Description:
------------
An array with a false or null element, joined, then used in sprintf
apparently causes PHP to crash. Actually, Apache cycles endlessly making
the OS think it has crashed.
This is the simplest expression I can create which causes the problem:
sprintf('%s',join('',array(false)));
Forcing the result of join into type string avoids the problem:
sprintf('%s',(string) join('',array(false)));
Reproduce code:
---------------
sprintf('%s',join('',array(false)));
Expected result:
----------------
I expected it to join all array elements (interpreting false and null
values as empty strings) and pass it to sprintf.
Actual result:
--------------
Apache cycled without responding to the page request. The Windows OS
interpreted this as a crash, although Apache did not actually stop
working or need to be restarted.
