Crash on ctx.call("DUMP", ...)

[gkorland]

Call to RM_CALL with command DUMP crashes on reply

ctx.call("DUMP", &["a"]);

The crash happens in this method:

 pub fn call<'a, T: Into<StrCallArgs<'a>>>(&self, command: &str, args: T) -> RedisResult {
        self.call_internal::<_, CallResult>(command, raw::FMT, args)
            .map_or_else(|e| Err(e.into()), |v| Ok((&v).into()))
    }
