Subject: [squeak-dev] VM crash when adding new instance variable to
MethodDictionary
To: <squeak-dev at lists.squeakfoundation.org>
Hi everyone,
we got the following issue.
Problem:
I get a VM crash when adding a new instance variable to the MethodDictionary
class.
Happens on 5.2 as well as on trunk.
Expected behavior:
Any of the following
1. It works
2. You get an error, that you may not change the instance variables of
MethodDictionary (as done on Collection and add a hint in the class comment
Steps to reproduce:
1. Add an instance variable to the MethodDictionary class
2. Save the change
Stacktrace:
(is from 5.2 but happens on trunk as well)
attached
Bests,
Björn
