Recursion and nesting level 1000 on dns resolve

[DangerLifter]

Sometime I got ths fatal when trying to resolve some names. It is not stable but repeatable error. Last time I was able to repeat it with doing resolve for "edu.tc".

Just doing:

$factory = new DnsResolverFactory();
$resolver = $factory->create('8.8.8.8', $loop);
$resolver->resolve('edu.tc');

Here is head ot backtrace. After this part same repeatable calls promise notify.
PHP Fatal error: Maximum function nesting level of '100' reached, aborting! in /var/www/projects/DomainScrapper/vendor/react/promise/src/Promise.php on line 140

Probably it is not issue of dns. Close for now. Will check more.

Your above test script works fine locally (promise is being rejected because name can not be resolved). Feel free to update this ticket if you manage to reproduce this, thanks!

Thank you for quick response. I found trouble in myself code. No problem with react. ;)
