`Equal` generation for anonymous structs results in a crash

[jamietanna]

package main

type ComplexStruct struct {
	Int      int
	MyStruct MyStruct
	Anon     struct {
		MyStruct MyStruct
	}
}

type MyStruct struct {
	Int64     int64
	StringPtr *string
}

func (this *ComplexStruct) Equal(that *ComplexStruct) bool {
	return deriveEqualComplexStruct(this, that)
}

Results in:
