Thanks for reporting! It looks like #44 is there again :-)

This was worked around via #53, but it looks like this was re-introduced via #61 and reactphp/stream#91. Note that #53 was actually only a work around, the real bug is actually #12.

For now, you may be able either downgrade to react/stream < 0.7 or react/dns < 0.4.9 to work around this again. Can you verify this?

For the reference: This is actually a bug in certain PHP versions on Windows only. This was fixed with PHP 7.0.17 and PHP 7.1.3.

See https://bugs.php.net/bug.php?id=74090 and php/php-src@89a5bd6.

This means that we have plenty of possible work arounds here, but I'd still like to tackle #12 which should ultimately fix this for all versions 👍

I tried the 0.4.8 version, it's ok @clue 👍

Will this be fixedin a future version? @clue

Will this be fixedin a future version? @clue

Absolutely! This is in fact already fixed in PHP, but once #12 is in, we will no longer rely on this fix alone and provide a more robust solution that also supports older PHP versions across all platforms 👍

Resolved via #74
