This test tests out the trace generated by the deployment of this contract:
```solidity
contract Revertor {
function run() public pure {
require(2 > 3, "This called failed");
}
}
contract Contract {
constructor() {
Revertor r = new Revertor();
r.run();
}
}
```
The trace should show a revert, with the revert reason for both the top-call as well
as the inner call.

Package native is a collection of tracers written in go.
In order to add a native tracer and have it compiled into the binary, a new
file needs to be added to this folder, containing an implementation of the
`eth.tracers.Tracer` interface.
Aside from implementing the tracer, it also needs to register itself, using the
`register` method -- and this needs to be done in the package initialization.
Example:
```golang
func init() {
register("noopTracerNative", newNoopTracer)
}
```
*/
package native
import (
"encoding/json"
"errors"
"github.com/ethereum/go-ethereum/eth/tracers"
)
// init registers itself this packages as a lookup for tracers.
func init() {
tracers.RegisterLookup(false, lookup)
}
// ctorFn is the constructor signature of a native tracer.
type ctorFn = func(*tracers.Context, json.RawMessage) (tracers.Tracer, error)
/*
ctors is a map of package-local tracer constructors.
We cannot be certain about the order of init-functions within a package,
The go spec (https://golang.org/ref/spec#Package_initialization) says
> To ensure reproducible initialization behavior, build systems
> are encouraged to present multiple files belonging to the same
> package in lexical file name order to a compiler.
Hence, we cannot make the map in init, but must make it upon first use.
*/
var ctors map[string]ctorFn
// register is used by native tracers to register their presence.
func register(name string, ctor ctorFn) {
if ctors == nil {
ctors = make(map[string]ctorFn)
}
ctors[name] = ctor
}

if ctor, ok := ctors[name]; ok {
