Here's a superficial patch. If an error occurs while determining the arguments,
it shouldn't try to determine which template is intended.


Patch: template.c, line 4542.

// Run semantic on each argument, place results in tiargs[]
+int olderrors = global.errors;
semanticTiargs(sc);
+if (global.errors != olderrors) return; // Quit immediately if error
occurs in argument

tempdecl = findBestMatch(sc);
if (!tempdecl)
{inst = this;
return;// error recovery
}

I guess this counts as an actual forward reference bug, given that Mix1 is
kind-of a forward reference

(This seems to be a variation of CRTP.)

(In reply to comment #0)
 this is slightly different code from Issue 402 and Issue 784, but 
 it causes the compiler to freeze in DMD 1.046 and 2.032:

Uh, 2.032 doesn't seem to have been released yet.
