Update the @expectedFailure decorator with additional bug info: 

rdar://problem/8542091 test/foundation: expr -o -- my not working?

Add an additional test for 'frame variable *self' when stopped in '-[MyString initWithNSString:]'
and move the 'expr -o -- self' to after MyString has been constructed and change it to
'expr -o -- my'.
