          Issue ID: 19123
           Summary: -allinst gives undefined reference linker errors
           Product: D
           Version: D2
          Hardware: x86_64
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P1
         Component: dmd
          Assignee: nobody at puremagic.com
          Reporter: zorael at gmail.com

Manjaro/Arch x86_64, dmd 2.081.1, ldc 1.10.0. run.dlang.io also shows the same
behaviour "since 2.080.1".

Reduced example, fails to link with -allinst but works without (dmd and ldc):

void main()
{
    import std.stdio;
    import std.datetime;
    writefln("%s", Clock.currTime);
}
