[Printer] Fixture crash on named argument usage on array_map() due to unpack arg flipped

[samsonasik]

Given the following code:

final class IncludeArrayMapNamed
{
    /**
     * @param int[] $items
     */
    public function run(array $items)
    {
        $result = array_map(array: $items, callback: fn ($item) => $item * 2);
    }
}

It currently got crash:

There was 1 failure:

1) Rector\Tests\TypeDeclaration\Rector\FuncCall\AddArrayFunctionClosureParamTypeRector\AddArrayFunctionClosureParamTypeRectorTest::test with data set #3 ('/Users/samsonasik/www/rector-...hp.inc')
assert($itemStartPos >= 0 && $itemEndPos >= 0 && $itemStartPos >= $pos)

Linked to php-parser getArg() method

The issue seems on Printer itself, so nothing todo with getArg(),

If it know about the information on named argument and its unpacked on print, it seems the issue on Internal PHPStan printer...

[samsonasik]

Closing for now as seems unrelated with rector, possibly on phpstan/php-parser internal side, as without getArg() call, the crash still happen on printing.

That was my initial suspicion from looking at it
