That patch was a bit too early in the function. Should be e2ir.c, line 3308.
Still in DelegateExp::toElem().

        {
            // Get pointer to function out of virtual table
            unsigned vindex;

            assert(ethis);
            ep = el_same(&ethis);
            ep = el_una(OPind, TYnptr, ep);
            vindex = func->vtblIndex;
+    if (vindex < 0)
+        error("Internal compiler error: malformed delegate. See Bugzilla
4860");

            // Build *(ep + vindex * 4)
            ep = el_bin(OPadd,TYnptr,ep,el_long(TYsize_t, vindex * 4));
            ep = el_una(OPind,TYnptr,ep);
        }
