          Issue ID: 19851
           Summary: std.concurrency linker errors with -dip1000
           Product: D
           Version: D2
          Hardware: x86_64
                OS: Linux
            Status: NEW
          Severity: regression
          Priority: P1
         Component: dmd
          Assignee: nobody@puremagic.com
          Reporter: zorael@gmail.com

With 2.086 my project no longer successfully builds with -dip1000. It still does with 2.085.1.

Dustmite reduced it to the following (https://run.dlang.io/is/JXsXMQ):

import std.concurrency;
import core.time;

void main()
{
    receiveTimeout(0.seconds);
}
