opencv memory leak detection

1. Static analysisWith static analysis, we can get the most initial insight into some of the code's non-canonical places or memory leaks, which is our first step in detecting memory leaks. Of course, there are some warnings that we don't care about to skip.2. Check for memory leaks with instrumentsThis method can roughly locate where we have a

Currently, an application that analyzes real-time traffic is developed in Linux, and a memory leak is found in the program during a joint test.This is anxious, will soon be on-line, fortunately found a valgrind tool, the perfect solution to the problem of memory leaks.Recommend you can use to see.Valgrind is a set of simulation-based program debugging and analysi

Instead of placing a call to _CrtDumpMemoryLeaks at each possible exit, you can include the following call at the beginning of the program:_CrtSetDbgFlag (_CRTDBG_ALLOC_MEM_DF | _crtdbg_leak_check_df);The statement automatically calls

; Nulgrind just shows developers how to create a tool. We will not do the introduction.Three use ValgrindValgrind is very simple to use and you don't even need to recompile your program to use it. Of course, if you want to achieve the best results, get the most accurate information, or need to recompile as required. For example , when using Memcheck, it is best to turn off optimization options. The format of the Valgrind command is as follows:Valgrind [valgrind-options] Your-prog [Your-prog opti

It helps to make your multithreaded routines more accurate. DRD is also a thread error detector. It is similar to Helgrind, but uses different analytical techniques, so it is possible to find different problems. Massif is a heap analyzer. It helps to make your program use less mem
