Hi! I've just added pull request on GitHub which fixes this problem.

Description:
------------
When running the below script on PHP 7.1.1, a segmentation fault occurs when calling
debug_print_backtrace().
There are 2 files below: 1.php and 2.php
To run it, run:
php 1.php
It seems to be related to the method aliasing for the trait for c2::f1 as f2. If that line is
removed, the script runs cleanly.
Test script:
---------------
1.php:
<?php
trait c2
{
public static function f1()
{
}
}
class c1
{
use c2
{
c2::f1 as f2;
}
public static function go()
{
return require('2.php');
}
}
c1::go();
=======
2.php:
<?php
debug_print_backtrace();
Expected result:
----------------
#0 require() called at [/tmp/1.php:19]
#1 c1::go() called at [/tmp/1.php:23]
Actual result:
--------------
#0 c1::Segmentation fault
