I posted a more generic version of this question to the xcode-users
mailing list, but didn't get anywhere...
I'm having a problem that is only occurring in Leopard. I have an
object that has an NSCalendar as a property. The calendar is copied
(rather than retained) from the sender.
The problem I'm having is its firstWeekday property value is
constantly being overwritten in memory from somewhere else, and I am
positive that it is not being overwritten by a set method, since
neither -setFirstWeekday: or the CF equivalent are being called on the
same calendar during the time that the value changes.
Normally I'd set a watchpoint on the memory address to find the
culprit, except that CFCalendarRef is an opaque data structure, and
even if the Leopard CF source code was available, CFCalendarRef has
always been a semi-private part of CF.
So I have two questions:
1. What's going on here? Why is the firstWeekday property being
overridden by something on Leopard, but not on Tiger?
2. How do I track down the culprit when I have no idea when I have no
idea what memory address the instance variable is using?
