Inifinite loop in blockEnd

The following code creates an infinite loop in blockEnd function:

```go

package main

import (
	"github.com/buger/jsonparser"
)

func main() {
	crasher := []byte(`{"a":[{"b":1},{"b":2},3],"c":{`)
	jsonparser.GetInt(crasher, "a", "b")
}
```

I can't find why for the moment. I continue my investigations :)
