Oops, that patch fixed a related test case:

struct S { int xx; }
int badline() { S s; return 100/s.xx; }
static assert(badline());

To fix this one as well, the same patch needs to applied to interpret.c,
getVarExp(), around line 1250.


            if (v->init)
            {
                if (v->init->isVoidInitializer())
                {
                        error(loc, "variable %s is used before initialization",
v->toChars());
                        return EXP_CANT_INTERPRET;
                }
                e = v->init->toExpression();
                e = e->interpret(istate);
            }
            else // This should never happen
            {
-                e = v->type->defaultInitLiteral();
+                e = v->type->defaultInitLiteral(loc);
                }
