Classification:Serious Bug Reproducible:Always
When you create a subclass in a test method (e.g. for mocking an object), overriding a method of this private subclass to access variables from the test case's context is not possible. Compilation fails.

Steps to Reproduce:
1. Add class to override with 1+ methods
2. Add new test suite and empty test case
3. Add variable, e.g. `expectation` to the test case
4. Override class and one of its methods within test case, set the variable from the test case's scope to another value

Expected Results:
The variable (e.g. `expectation`) obtains its new value if the method in question of an instance of the private subclass is invoked.

Actual Results:
Segmentation fault: 11

Xcode Version 6.3.2 (6D2105)
