Check paniced when using OneGenOf

[vedujoshi]

Sometimes we get a failure with the below code

Error on property evaluation after 1 passed
   tests: Check paniced: reflect: Call using *schema.PathMatcherType_Prefix
   as type *schema.PathMatcherType_Path

Could you please suggest if you see any issue ?

Code:

func genPathMatcherType() gopter.Gen {
	return gen.StructPtr(reflect.TypeOf(&pb_schema.PathMatcherType{}), map[string]gopter.Gen{
		"PathMatch": gen.OneGenOf(genPathMatcherType_Prefix(), genPathMatcherType_Path(), genPathMatcherType_Regex()),
	})
}
func genPathMatcherType_Prefix() gopter.Gen {
	return gen.StructPtr(reflect.TypeOf(&pb_schema.PathMatcherType_Prefix{}), map[string]gopter.Gen{
		"Prefix": gen.AlphaString(),
	})
}
func genPathMatcherType_Path() gopter.Gen {
	return gen.StructPtr(reflect.TypeOf(&pb_schema.PathMatcherType_Path{}), map[string]gopter.Gen{
		"Path": gen.AlphaString(),
	})
}
func genPathMatcherType_Regex() gopter.Gen {
	return gen.StructPtr(reflect.TypeOf(&pb_schema.PathMatcherType_Regex{}), map[string]gopter.Gen{
		"Regex": gen.AlphaString(),
	})
}

It looks right to me (provided the structs have these string fields).
Do you have more information where the panic occurs?
