https://issues.dlang.org/show_bug.cgi?id=19123 --- Comment #4 from Mike Franklin <slavo5150@yahoo.com> --- I've narrowed this down somewhat. What's happening is `-allinst` causes symbols to be emitted to the object file that otherwise wouldn't be. Those symbols, however, call other symbols, and it's those other symbols that aren't being emitted for some reason, resulting in linker errors. --

--- Comment #6 from GoaLitiuM <goalitium@dissues.mail.kapsi.fi> ---
I recently hit a bug similar to this one, if not the same one, with this following code:

import std.variant;
import std.typecons;

struct S {}
void main()
{
    alias T = Typedef!(S, S.init);
    Variant v = T();
}
