[OBJC newbie] - Intance variable becomes 'invalid'

Just learning OBJC...

I have a class with an NSString * instance variable.
Class has two methods, method a sets a value into the string, when method b is called and tries to access the string it crashes my app. gdb says the string instance is 'invalid'.
How can an instance variable become invalid? What does it even mean?
I suspect that since OBJC uses pointers everywhere that the instance got stamped on somehow?
I have been living in the safe world of Java for too long I fear.
