Thank you for the report, and for helping us make PHP better.
Yes, I introduced that regression in svnrev, 314943 and it should now be fixed
per
314981.

Looks like there is a big hole in our test coverage :-/
Thanks for reporting!

Log: Bug #55424 Fatal error when calling a method from a trait that is defined
in parent class and required by using an abstract method in the trait.
# The method got unconditionally deleted from the class, since it was assumed
that we override it, but we did not in case of abstract methods coming from a
trait. Thus, dont delete when we try to merge in an abstract method.

With the same test script, I'm getting this error:
Fatal error: Cannot make non abstract method Input::setAttribute() abstract in
class Text in /www/temp.php on line 27

Description:
------------
A fatal error occurs when a method is called from a trait, which is implemented
in the parent class of the class that utilises the trait.
Feels related to #55355 that was fixed.
Test script:
---------------
<?php
trait Required
{
function setRequired()
{
$this->setAttribute('required', true);
return $this;
}
abstract function setAttribute($name, $value);
}
class Input
{
protected $attributes = [];
function setAttribute($name, $value)
{
$this->attributes[$name] = $value;
}
}
class Text extends Input
{
use Required;
}
$t = new Text();
$t->setRequired();
Expected result:
----------------
No fatal error.
Actual result:
--------------
PHP Fatal error: Call to undefined method Text::setAttribute() in
/home/jared/Temp/trait2.php on line 7
Fatal error: Call to undefined method Text::setAttribute() in
/home/jared/Temp/trait2.php on line 7
