The code attempts to read a non-existent field, and also attempts to use a with
statement on a symbol that doesn't exist (usually an enum would be used)

-----
struct Event { }

void main()
{
    Event event;
    switch (event.type) with (En)
    {
        default:
    }
}
-----

test.d(8): Error: no property 'type' for type 'Event'
test.d(8): Error: '__error' must be of integral or string type, it is a _error_
test.d(8): Error: undefined identifier En
test.d(8): Deprecation: non-final switch statement without a default is
deprecated

After the errors DMD crashes. It's also interesting that the non-final switch
error occurred, even though there is actually a default switch in the code. The
__error's in the diagnostics should likely not show up to the user as well.
