Hi
I extracted a superclass and now I get a MNU during image startup because I have an instance of the now abstract base class in the start up list.
The image comes up for a fraction of a second and the crashes (PharoDebug.log). Any idea of how I can recover from this?
One way is in gdb put a breakpoint in the MNU processing (createActualMessage). Then when you hit the MNU edit the message object to something harmless such as Message selector: #class arguments: #(), and proceed. This isn't easy. You have to learn how to find symbols in the VM (you'll need to find eg. #class) and how to store pointers in an object. So only consider doing this if the image is worth a few hours learning arcane VM innards, and possibly building a debug VM that'll be less fragile in gdb.
Cheers
