Summary: Incorrect warning: expression result unused

I get this warning when building the code below with Clang 1.6:
warning: expression result unused [-Wunused-value]
for (NSUInteger j = finish; j >= start, j != NSUIntegerMax; j--) {
~ ^ ~~~~~
I am absolutely sure that the expression is indeed used so even if I am doing
something funky the warning is incorrect.

NSUInteger finish = 10;
for (NSUInteger j = finish; j >= start, j != NSUIntegerMax; j--) {
NSLog(@"%C\n", [text characterAtIndex:j]);
}
[pool drain];
return 0;
}
