Bug description: Strange behaviour after setting stream_set_blocking()
Description:
------------
When running a PHP script as CLI, after setting stream_set_blocking($x,0),
invoking an infinite loop which includes a print statement causes
spontaneous script termination after an indeterminate number of
iterations.
Omitting stream_set_blocking() eliminates the problem.
Tested and confirmed this behaviour on PHP 5.2.3 and PHP 5.2.5 on several
FreeBSD systems.
Reproduce code:
---------------
This works as expected:
<?php
stream_set_blocking(STDIN,0);
do {
} while(TRUE);
?>
However, after introducing a print statement to the loop, the script
appears to spontaneously terminate after a number of iterations.
<?php
stream_set_blocking(STDIN,0);
do {
print "!";
} while(TRUE);
?>
Expected result:
----------------
Script should loop indefinately.
Actual result:
--------------
Script terminates on it's own. Any code following the loop is not
executed.
