Hi, I have a model that comprises two stores. 1. A read only store
of a large data-set (this is read only as it is a public dataset
shared among users) and 2. A read-write store that is the result of
creation by user actions. One of my managed objects can belong to
either store. Du

Hi all,
I've been trying to track down a bug and it *seems* that it might be
CoreData's fault (I highly doubt it but there's a small chance). I
have the following configuration:

- A subclass of Base, let's call it Subclass
Subclass has a to-many relationsh

Note that this only applies to saved objects which have been persisted
to a store (or maybe have had a persistent ID generated?). Sadly I
don't think there's any API for knowing which store an object will be
assigned to when saved, short of calling -assignO

What is the value of val at the time the crash occurs? Will it
always convert to 9 digits or less?
What value is sprintf() returning?
You might want to use snprintf() or asprintf().

In this case val was exactly nine digits: 213294334. But it can also
be greater sometimes.
Sprintf() is returning the same value, using %d on 10.5.

Sprintf() is returning the same value, using %d on 10.5.
I meant sprintf()'s returned int value, which is the count of
formatted output chars, not including the trailing null. Read 'man
sprintf'.
Or just try the simple expedient:
char str[80];
-- GG

It would be best to convert all your sprintf calls to snprintf, which
is a safer equivalent that won't overflow the buffer. If the value is
too long to fit, it'll be truncated instead of overflowing and
corrupting the stack. (This type of overflow is one of the main causes
of security holes

Right, it was a buffer overrun. Simple as that. Thanks guys!

A classic (but non-traditionally-Cocoa) way to deal with this problem
is with #ifndef preprocessor statements. You make up a preprocessor
symbol for each include file -- I often use the include-file name in
all capitals, with some "__"s bracketing it. Then you use it as
follows. Suppose
This does not solve the problem at hand (two interfaces need a
