Description:
------------
If the callback for readline_completion_function returns an empty array, php will segfault.
When running the example code, hit tab to fire the callback.
Test script:
---------------
<?php
readline_completion_function('readline_callback');
do
{
$command = readline('> ');
echo 'command: ' . $command . PHP_EOL;
} while ($command);
function readline_callback($command)
{
return [];
}
