- Dear MacAppers,
-
- A few weeks ago I stumbled across the dreaded Jump Table overflow problem with
- -Debug. I responded by using -NoInspector -Debug, and using Jasik's Debugger
- (which provides all the inspector features anyway); this dropped the jump table
- entries to below 4096, and all was roses.
-
- This worked fine until today, when I (finally!) switched to MacApp2.0 final,
- and found that with -NoInspector -Debug, I have 4200 jump table entries.
- Goodbye -Debug.
-
- So, I ask the question, does the promised ETO linker/compiler really fix this
- problem? I can't get ETO in Australia by normal channels yet, but if this
- compelling reason for getting it exists, perhaps I'll will find a way.
-
- Question 2. I seem to recall in the dim distant past some assertion that all
- object methods create a jump table entry. Is this true? Or do they still need
- an intersegment call to create the entry?
-
- Thanx,
-
