          Issue ID: 20802
           Summary: [REG2.088.0] Link failure with writefln
           Product: D
           Version: D2
          Hardware: x86_64
                OS: Linux
            Status: NEW
          Severity: regression
          Priority: P1
         Component: dmd
          Assignee: nobody puremagic.com
          Reporter: tim.dlang t-online.de

The following code worked with 2.087.1, but doesn't link since 2.088.0:

//////////////////// test.d ///////////////////
import std.uni, std.stdio;

class C
{
    size_t number;
}

int main()
{
    C inst;

    mixin({
        while(false)
        {
            dchar current;
            CodepointSet(current);
        }
        return "";
    }());
    writefln("%d %d %d", inst.number, C.sizeof, inst.number );
    return 0;
}
///////////////////////////////////////////////

With 2.088.0 it produces the following link error:

It may be related to issue 17155, but since it was introduced in a different
release I have created a separate issue.
