甚至在这个内存释放之前,namestr值就一就已经被变更,那也是为什么Purify报告一个MLK(内存渗漏)错误的原因。
Even before freeing the memory, the value of namestr has been changed, and that is why Purify reports an MLK (memory leak) error.

结果是,即使内存在释放后立即被覆盖,并且新指向的值不同于预期值,也很难识别出新值是错误值。
The consequence is that, even if memory is overwritten immediately on freeing and the new pointed value differs from the expected one, the new value might be hard to recognize as erroneous.
避免在处理器中释放内存的最好方法是,标记或记录将要释放的对象,让程序不间断地检查是否有等待被释放的内存。
The best way to avoid freeing memory in a handler is to flag or record the objects to be freed and have the program check from time to time whether anything is waiting to be freed.
