A one-line change in 2.034 which caused the regression. I think it's because
c *= -1; becomes NEGATE c, which isn't a binary operation. Here's a patch which
undoes the change. I'm not sure which bug it was attempting to fix.

gother.c, line 480, inside chkprop().

        if (d->Eoper == OPasm)          /* OPasm elems ruin everything  */
            goto noprop;
-        if (OTassign(d->Eoper) && EBIN(d))      // if assignment elem
+        if (OTassign(d->Eoper))      // if assignment elem
        {   elem *t = Elvalue(d);

            if (t->Eoper == OPvar)
