Why .NET String is immutable? [duplicate]
...ector.
The last lines are...
int length = str0.Length;
string dest = FastAllocateString(length + str1.Length);
FillStringChecked(dest, 0, str0);
FillStringChecked(dest, length, str1);
return dest;
As you can see the FastAllocateString returns an empty but allocated string and then it is modified...
How does Java Garbage Collection work with Circular References?
... interpreter: shell scripts typically only run for a few seconds and don't allocate much memory.
Combine your reference counting garbage collector with another garbage collector which doesn't have problems with cycles. CPython does this, for example: the main garbage collector in CPython is a refere...

Long answer: You should never nil out properties in dealloc, even in manual memory management.
In MRR, you should release your ivars. Nilling out properties means calling setters, which may invoke code that...
Why use static_cast(x) instead of (int)x?
...4 bytes
Since this results in a 4-byte pointer pointing to 1 byte of allocated
memory, writing to this pointer will either cause a run-time error or
will overwrite some adjacent memory.
*p = 5; // run-time error: stack corruption
In contrast to the C-style cast, the static cast will...

I can only add that how you allocate your budget of 7000 executions (e.g., .repeat(7, 1000) vs. .repeat(2, 3500) vs .repeat(35, 200) should depend on how the error due to system load compares to the error due to input variability. In the extreme case if...
