How does valgrind work? - Stack Overflow
Nov 1, 2009 · Valgrind provides wrappers around the system call and registers for pre and post callbacks for every system call to track the memory accessed as part of the system call. Thus, Valgrind is a OS abstraction layer between the operating system and the client application. The diagram illustrates the 8 phases of Valgrind :
Memory/Address Sanitizer vs Valgrind - Stack Overflow
Nov 13, 2017 · Can anyone tell the main features, differences and pros/cons of Sanitizer and Valgrind? Edit: I found some of comparisons like: Valgrind uses DBI(dynamic binary instrumentation) and Sanitizer uses CTI(compile-time instrumentation). Valgrind makes the program much slower(20x) whether Sanitizer runs much faster than Valgrind(2x).
Is it possible to make valgrind ignore certain libraries?
Jul 4, 2010 · Since valgrind malloc is injected directly into the program text -- not loaded as a dynamic library -- it appears in the stack the same way as your own code does. This allows Valgrind to track the allocations, but also makes it harder to do exactly what you have asked. FYI: I am using valgrind 3.5.
Terminate process running inside valgrind - Stack Overflow
There is no "inner process" as both valgrind itself and the client program it is running execute in a single process. Signals sent to that process will be delivered to the client program as normal. If the signal causes the process to terinate then valgrind's normal exit handlers will run and (for example) report any leaks.
How to detect segmentation fault details using Valgrind?
Apr 21, 2010 · Valgrind will show you the stack backtrace of where segmentation fault occured. After that it's up to you to find what happened and to correct it. In your code, regardless of valgrind, I would check what returns cont[ "some_key" ] the most likely cause of your segfault is that the returned value is some wild pointer or not initialized at all.
Are there known false positives issues with Valgrind?
Jul 10, 2012 · The false positives may arise if you are using older valgrind with newer gcc and glibc, i.e., valgrind 3.3 with glibc 2.9. Having said that, you still have to look into issue and find out if it is really a false positive (if that turns out to be the case, you can write a suppression for it yourself) or is it a real bug in your program.

Valgrind for Windows / Wiki / Home - SourceForge
Mission Statement. This project aims at making the Valgrind tool suite available on Microsoft Windows. The project founder believes that is it technically possible to run Valgrind natively on Windows, and that a coordinated, collaborative effort by open source developers will eventually deliver a stable and production-ready release.
