where is the memory leak in the code below?

wish of those help You allocate a memory block we'll call BLOCK1. p initially points to BLOCK1. You allocate a memory block we'll call BLOCK2. buf initially points to BLOCK2. buf is changed to point to BLOCK1 (buf = p;). Nothing points to BLOCK2 now. Memory leak. You free BLOCK1 (free(p)), but you never free BLOCK2.
Also, you invoke undefined behaviour by attempting to free a block that has already been freed (free(buf)).

wish helps you Yes you have to add a release in the ClassB dealloc cause you make a retain on strB in the setter.

Xcode 4 Memory Leak Instrument how to get line of code where leak occurred

wish of those help If your code leaks memory, you will see your relevant methods in the details tab, right where you are looking. They are displayed in black as opposed to methods in the APIs which are gray. You can't look into API Methods of course, hence the assembly code. If there is really something wrong in your code, set the slider on the bottom of the tab on the rightmost position and you should see the concerned methods.
If still none of them are in your code, you probably just don't leak anything. (There are actually not many scenarios in which ARC-Code can leak memory. Retain cycles are probably the most common one) I stumbles over one or two cases in which an API was 'leaking' memory. There is really nothing you can do about it and most likely, it's just a false positive anyway rather than a real leak. If you are only 'leaking' a few bytes, I wouldn't worry about it.

Potential memory leak in Java, may this code lead to the memory leak?

it should still fix some issue There will be no leaks in your code as long as the drv object does not maintain references to objArr. The reference objArr to your "heavy object" is limited to the scope of the while loop, and thus once you leave an iteration, it is eligible for garbage collection. However, if drv maintains a permanent reference to the object, then it will not be collected as long as the reference persists.
The example in the link you mention is when the reference to your data lives outside the scope (in their example, the E[] array field of the Stack class) and cannot be collected.

Is there any code snippet demonstrate the harm of memory leak or fogeting free memory malloced

I hope this helps you . Okay I will explain the problem.
Computers has limited memory ( modern personal one has about 8 Gigabytes). Operating systems and apps need the memory so their code can be loaded into it and executed by the CPU. Modern systems split the memory into equally sized chunks called pages, the actual page size differs from system to another

To fix the issue you can do I was facing the same issue but then I realized that the tool doesn't show any leaks though there are some leaks.
Like in the following case:
