So I had this bug the other day that I thought would make an interesting
riddle.
The code looked like this:
#define SAFE_SET(old, new) [new retain]; [old release]; old = new;
...
- (void) foo : (NSString*)path {
SAFE_SET(m_Path, [path lastPathComponent]);
}
Now the problem was any time I accessed m_Path my app would crash. This
isn't cocoa specific, I'm just dumb for using macros where I should have
been using a function. Can anyone guess what the problem is ?
good luck !
Sailesh
