    A powerful tool for troubleshooting memory problems under Linux
    1. Memory Leak Memory leak (MemoryLeak) means that the dynamically allocated heap memory in the program is not released or cannot be released by the program for some reason, resulting in a waste of system memory, leading to serious consequences such as slowed down program running or even system crash. Characteristics: Concealment: Memory leaks occur because memory blocks are not released, which is an omission defect rather than a fault defect. Cumulative memory leaks usually do not directly produce observable error symptoms, but gradually accumulate, reducing the overall performance of the system. In extreme cases, the system may crash. The most intuitive question is why our program starts running normally and then exits abnormally after a while. Memory leaks do not refer to the physical disappearance of memory, but rather to the fact that after the application allocates a certain amount of memory, due to incorrect use,
