The following code is compiled without warnings, in spite of 4711 not being
defined by enum. If the default-case will be omitted, the expected warning
appears.
int main(int argc, char** argv)
{
enum Enum { a };
Enum test = a;
switch(test)
{
case 4711:
break;
default:
break;
}
return 0;
}
--
Summary: switch/case does not detect invalid enum values if
default-case is used
