This is not a bug; your code is a LSP violation which had been fixed in bug #71428.
In the concrete example, the Foo::bar() function can be passed null, but Hello::bar() cannot.
[This is something we try to fix with nullable parameters/null unions in 7.1.]

This was changed in commit e9d65160 by Dmitry. It appears to be a fix for a different bug (71978).

Description:
------------
I wanted to raise this against 7.0.6, but it was not available in the list above, despite being released?
There seems to be a regression in interface method declaration compatibility checking.
The below test script only fails on 7.0.6.
It also only fails if the $baz is type hinted as array.
Test script:
---------------
<?php
interface Foo {
public function bar(array $baz = null);
}
class Hello implements Foo {
public function bar(array $baz = [])
{
}
}
Expected result:
----------------
N/A
Actual result:
--------------
Fatal error: Declaration of Hello::bar(array $baz = Array) must be compatible with Foo::bar(array $baz = NULL) in /in/VhEtd on line 7
Process exited with code 255.
