• Memory Safe or Bust?

  Continuous Integration and Continuous Deployment [CI/CD] pipelines play a crucial role in enforcing code quality, especially when working with memory-unsafe languages. By integrating automated dynamic analysis tools like Valgrind or AddressSanitizer, static analysis tools like Clang Static Analyzer or cppcheck, and manual code review processes, developers can identify and mitigate many memory-related... - Source: dev.to / 30 days ago

• Top 7 C++ Tools to explore in 2024 if it's not already the case.

  Valgrind is an open-source tool designed to help developers identify memory management issues, memory leaks, and various other types of memory-related errors in their programs. It's commonly used for debugging and profiling purposes, particularly in C and C++ development. Here's an overview of Valgrind:. - Source: dev.to / 2 months ago

• Debugging OpenGL with GDB causes shader issues

  Valgrind is a tool for debugging memory errors. We have it installed on our linux machines at work. I'm not sure how difficult this is to install and setup. You can find more info here: https://valgrind.org/. Source: 5 months ago

• Ask HN: Good practices for my first C project

  It's often best not to think too much about "aesthetic", or performance, at first, and to focus instead on getting something that works, correctly. FWIW, The Mythical Man-Month[0] recommends to start with a few throw-away prototypes, during which you're gaining expertise over the problem, that you can later crystallize in more definite versions. Now, it doesn't mean good practices should be discarded... - Source: Hacker News / 6 months ago

• C++ is everywhere, but noone really talks about it. What are people's thoughts?

  I think you're on the right path, yes. Usually I use Valgrind for all memory related debugging, not sure if it can help you here. Source: 10 months ago

• Is malloc_trim() safe to use?

  Have you tried using tools like ASAN/LSAN or valgrind to confirm that there are indeed no memory leaks? Source: 12 months ago

• Testing Vlang, Rust and Zig and more!

  Tested my silly app with Valgrind and for few minutes run I had around 2 MB of memory leak. - Source: dev.to / 12 months ago

• Why So Slow? Using Profilers to Pinpoint the Reasons of Performance Degradation

  First, we used Callgrind to get some results. Using Callgrind massively slowed down the execution. In some cases, it was almost 20 times slower than the unprofiled version. Callgrind is based on Valgrind, which uses dynamic binary instrumentation to inspect and control different aspects of applications, causing a significant slowdown. We used KCachegrind to interpret and visualize the reports generated by... - Source: dev.to / about 1 year ago

• trouble fixing memory leak in C..

  If you post your actual code, somebody might be able to help you spot the problem. You could also try running your program under a memory checker like Valgrind. Or you could just add debug logs with the addresses of the objects that you're allocating/freeing, so that you can track down where they don't match up. Source: over 1 year ago

• Concatenating two linked lists

  In addition to a debugger, you can use a memory checker like Valgrind to more precisely narrow down the source of illegal memory accesses. Source: over 1 year ago

• What could cause a program to not work in debug mode, but release mode works just fine?

  Since everyone else has gone into great detail, now is a good time to learn about Valgrind (specifically memcheck). It can help you find memory-based issues with your code. Source: over 1 year ago

• From Novice to contributor to Linux Kernel and/or other Low-Level projects

  You can also use tools like Valgrind (https://valgrind.org/) or Asan (https://en.wikipedia.org/wiki/AddressSanitizer) to execute applications and look for possible leaks or other issues reported (such as invalid memory accesses and such). Source: over 1 year ago

• Modern C++ Won't Save Us · Alex Gaynor

  But beyond std::shared_ptr, the post doesn't address modern mitigations like increasingly smarter static analysis (better compiler warnings and linting tools), runtime analysis like AddressSanitizer and Valgrind, and best practices like the C++ Core Guidelines to try to learn from the language's long history and past mistakes. These things make a big difference in making C++ a usable language. Source: almost 2 years ago

• The Curious Case of the Disappearing “if”

  My next step was to try Valgrind — nothing useful. I also tried address and undefined behavior sanitizers — also nothing useful. Now what? - Source: dev.to / almost 2 years ago

• I taught myself C from K&R ANSI C but will now be working a contemporary C project this summer. How would you recommend I catch up on modern C?

  Valgrind is also a great tool for debugging, especially in case of memory leaks in my experience. Source: about 2 years ago

• How to make develop C application easier?

  If the problem you have is the allocation/deallocation of memory, you can use tools like Valgrind https://valgrind.org/ That’s a tool that works on Linux and MacOS X for instance, and you use it like this: valgrind --leak-check=yes "your-program-executable" When "your-program-executable" exits, it will show you which blocks of memory were allocated (malloc) but not freed.
