Bug 21114 – core.exception.AssertError@std/socket.d(1004): Assertion failure

This happens constantly when running the test suite. Environmental errors should NOT produce assert fails.

@CyberShadow updated dlang/phobos pull request #7580 "Improve behavior of std.socket "soft" unittests" mentioning this issue: - std.socket: Hide details of "soft" unittests unless built with -debug=std_socket Reduce noise and false alarms in CI logs. Also improve the printed message on failure, to make it clear that it is likely a random failure, and that the ignored test failure is not what's causing the entire test suite run to fail. Fixes Issue 21114. https://github.com/dlang/phobos/pull/7580
