 Thanks for reporting
 Abdelghani.Now it would be doubly useful if you could
 isolate which build introduced the
 problem.PharoLauncher can be used to help bisect
 working/non-working images.

 Subject: Removing instance variables doesn't recompile
 the methods
 
 Hi,
 
 In
 a fresh pharo 6 image, I add a class with an instance
 variable x and implement accessors.
 Then
 I write a test method for the accessors of x
 MyClassTest>>testReadWriteX
    
 self assert (MyClass new x: 0) x equals: 0
 
 I
 run the test and obviously it is green
 
 BUT
 
 I
 remove the instance variable x. Obviously, the accessors are
 broken and the test should be red when I execute it again
 but it is not!!!
 
 I
 can even change the class again (to recompile it I thought)
 or even load the code in a new image and the tests are still
 green. 
 I
 can also invoque the broken methods in a playground or in an
 inspector : MyClass new x: 0; increment; x then printIt. and
 astonishingly 1 is printed.
 The
 only way to detect the error is to recompile the method but
 this does not happen (maybe it should) when instance
 variables are modified or removed in the class (even when
 you use the refactoring tool!) 
 
 I
 think this is annoying because one can no more really trust
 his tests.
 
 Cheers
 Abdelghani
