@ngdoc error
@name $compile:infchng
@fullName Unstable `$onChanges` hooks
@description

This error occurs when the application's model becomes unstable because some `$onChanges` hooks are causing updates which then trigger
further calls to `$onChanges` that can never complete.
AngularJS detects this situation and prevents an infinite loop from causing the browser to become unresponsive.

For example, the situation can occur by setting up a `$onChanges()` hook which triggers an event on the component, which subsequently
triggers the component's bound inputs to be updated:

```html
<c1 prop="a" on-change="a = -a"></c1>
```

```js
function Controller1() {}
Controller1.$onChanges = function() {
  this.onChange();
};

mod.component('c1', {
  controller: Controller1,
  bindings: {'prop': '<', onChange: '&'}
}
```

The maximum number of allowed iterations of the `$onChanges` hooks is controlled via TTL setting which can be configured via
{@link ng.$compileProvider#onChangesTtl `$compileProvider.onChangesTtl`}.
