I've extended the test to reflect what happens in our App and now the problem
shows:
Code:
#import <Foundation/Foundation.h>
int
main(int argc, char **argv)
{
NSString *s = @"fi-rst|sec-ond|thi-rd",*s1;
NSArray *a,*a1;
NSAutoreleasePool *pool =[NSAutoreleasePool new];
a = [s componentsSeparatedByString:@"|"];
s1 = [a objectAtIndex:0];
NSLog(([NSString stringWithFormat:@"a %@ has retainCount of %i",s1,[s1
retainCount]]));
a1 = [s1 componentsSeparatedByString:@"-"];
NSLog(([NSString stringWithFormat:@"b %@ has retainCount of %i",s1,[s1
retainCount]]));
[[a1 objectAtIndex:0]retain];
NSLog(([NSString stringWithFormat:@"c %@ has retainCount of %i",s1,[s1
retainCount]]));
[s1 retain];
NSLog(([NSString stringWithFormat:@"after [s1 retain]: %@ has retainCount
of %i",s1,[s1 retainCount]]));
[pool release];
NSLog(([[NSString alloc]initWithFormat:@"after [pool release]: %@ has
retainCount of %i",s1,[s1 retainCount]]));
exit (0);
return 0;
}

the substrings of a substring retain their string from which they where
splitted off;
when those 2nd generation substrings are retained, the 1st generation
substrings won't get deallocated;
but they should, they are just intermediate objects;
