I am currently having an issue with my existing C++ code, specifically experiencing issues in malloc and tcp connection . This project entails finding and rectifying this issue to ensure efficient operation. This job will require you to dive into an already existing C++ codebase, put logs identify the problem with our runtime, and implement a fix. We have the c++ code already with us , it has a module cold udp which is custom-developed, the problem is that when udp is run it throws this error sometimes when packets come from tracker : TELT: Total Packets received = 1 Sent Packet No : 1, Bytes Count for the packet : 127TCPComm::Error reading TCP/IP Connection closed *** Error in `./udp_d': double free or corruption (!prev): 0x00007f24d00238c0 *** Abort Signal Captured...terminating AVL Array length : 83 TELT: Total Packets received = 1 Sent Packet No : 1, Bytes Count for the packet : 93 Thread Complete : [login to view URL]:17637TCP Communication timeout ocurred in Poll Thread Complete : [login to view URL] AVL Array length : 117 TELT: Total Packets received = 1 Sent Packet No : 1, Bytes Count for the packet : 127 Thread Complete : [login to view URL] Key requirements include: * Strong knowledge of C++ * Experience with debugging * Familiarity with common C++ runtime errors and their solutions * Able to work on an existing codebase, understanding its style and structure Past proof of similar tasks completed would provide additional assurance. Your attention to detail and persistence would be greatly beneficial for this task. Looking forward to your impressive proposals.

Hello, I am a 20+ yers experienced C and C++ Engineer, and C++ Trainer. Memory allcocation errors using malloc, calloc, new etc are common in C/C++. pointers that are allocated to more than once too can cause erros. Pointers thqat are not set to NULL too (before being used), can often cause errors in older compilers. Can I take a look at the buggy code?

@joelvibert5

Good morning. I am new on this site, but am a French engineer with over 30 years of programming and debugging experience, mostly in C/C++. I have already worked on multithreaded UDP code and have dealt with several cases of double memory releases and memory corruption, which is clearly what you face here. If the memory is released twice, it should be easy to fix. It is trivial if the bug is within one thread, otherwise, it could require adding synchronization. In the case of a corruption, it can be tricky - there is no method that works in all cases -. However, I've already tackled such situations, and with code instrumentation, there is a high chance your bug can be found. Even just code inspection might work. Anyway UDP code is usually rather small. The most important thing is the environment. You didn't indicate the OS you are using for development, which is of uttermost importance for developers. I would be glad to help you with your project, but can only work on your code if it can be compiled and run on Windows - my favorite, especially if you use Visual Studio instead of gcc - or on a Ubuntu virtual machine. In case you choose to work with me, could you provide me with a use case in which the bug is easy to reproduce? Expecting to hear from you soon, yours sincerely, Joël Vibert

I am from a core C++ background, so I would think that delivering it on time should be the goal. So if setting up the actual environment takes 1-2 days and unit testing make take another 2 days, the project should complete in less than 7 days.
