The file crashing the fixer:

So i removed this three fixer causing the issue:

<exclude name="SlevomatCodingStandard.Namespaces.UselessAlias"/>
<exclude name="SlevomatCodingStandard.Namespaces.AlphabeticallySortedUses"/>
<exclude name="SlevomatCodingStandard.Namespaces.UseSpacing"/>

Now I have:

I'm sorry I'm not able to reproduce the error. Please provide failing test and then reopen the issue.

[soullivaneuh]

@theofidry I see you had a similar problem in #526.

Did you find any clue?

[theofidry]

Nope, couldn't find the time to dig into it at all :/

[kukulich]

@soullivaneuh @theofidry It's probably bug in PHPCS itself.

[soullivaneuh]

Here is a dump of $token when the exception occur:

array(8) {
  ["code"]=>
  int(361)
  ["type"]=>
  string(7) "T_CLASS"
  ["content"]=>
  string(5) "class"
  ["line"]=>
  int(11)
  ["column"]=>
  int(7)
  ["length"]=>
  int(5)
  ["level"]=>
  int(0)
  ["conditions"]=>
  array(0) {
  }
}

[kukulich]

Yes, it's really bug in PHPCS itself. T_CLASS token should have scope attributes.

[soullivaneuh]

It's probably bug in PHPCS itself.

@kukulich Maybe. The scope_closer existence is not checked on the failing source file. Do you expect to always have it?

[kukulich]

Yes, because you cannot write class definition without { and }

[soullivaneuh]

Right, I think I found the related issue: https://github.com/squizlabs/PHP_CodeSniffer/issues/2142#issuecomment-476140225

Thanks for your time @kukulich!
