[PHP-BUG] Bug #71229 [NEW]: Writing to "php://stdout" from the interactive shell makes it hang

From:             michelezamuner at gmail dot com
Operating system: Ubuntu 14.04.1 x86_64
PHP version:      7.0.1
Package:          *General Issues
Bug Type:         Bug
Bug description:Writing to "php://stdout" from the interactive shell makes it hang

Description:
------------
In the interactive shell, after executing a function that writes a
string to "php://stdout" file, the prompt doesn't appear back, and no
input from the keyboard is recognized. The only thing left to do is
terminating the process (Ctrl+C) and starting the shell again.

Test script:
---------------
// Start the interactive shell
// $ php -a
file_put_contents("php://stdout", "Hello, World!");
// The string is correctly printed, but no prompt is available any
more,
// and no keyboard input is recognized.

Expected result:
----------------
After printing the expected string (which happens correctly) I expect
the prompt "php > " to be available again, and to be able to continue
working with the shell.

Actual result:
--------------
The prompt "php > " doesn't appear after printing the string, and the
shell is frozen, not accepting any input from the keyboard.
