module test;

import std.stdio;

enum E { a }

string get()
{
    auto e = cast(E)123;
    final switch(e)
    {
        case E.a:
            return "foobar";
    }
}

void main()
{
    writeln(get());
}

$ dmd -run test.d
> core.exception.SwitchError at test(10): No appropriate switch clause found

$ dmd -release -run test.d
> x ↑

The release switch ends up making get() return garbage.
