Is that something that should be merged to upstream Valgrind?

And sadly that was one that I broke trying to refactor together all our C++ autoconf tests. Silver lining, I added a test for it so if I break it again we should notice earlier.

"some community effort" is a huge understatement. Let me rephrase that for you: "Possibly the largest ever single contribution to Valgrind". Initial work on this was started by an …

Just a minor point release, mainly for a regression that I introduced :-( The following bugs have been fixed or resolved in this point release. 519574 valgrind 3.27 "--fair-sched=y…

AI slop.

We still use KDE's bugzilla. One of the reasons that Vagrind was initially developed was to help with KDE back when many developers didn't really understand how to use new and dele…

There was someone at Intel working on AVX512 support in Valgrind. She is/was based in St Petersburg. Intel shuttered their Russian operations when Putin invaded Ukraine and that pr…

The problem is that there are many many people that are falling over themselves to believe bogus claims about false positives. Outside of Valgrind bugzilla bug reports these claims…

I'm working on Valgrind on macOS, integrating Louis Brunner's work and trying to add a few more fixes. In 2025 support for macOS Intel 10.14, 10.15 11 and 12 was added. Intel macOS…

If anyone can help adding AVX512 (and other CPU features) support then that would be most welcome. It’s a major task though.

> even with Valgrind and similar tools, you are still going to run into weird destructor issues with inheritance. I love these folklore comments. Post an example.

In my experience that is usually the result of years and years of accumulation of shit code. The results is thousands of leaks. That makes detection of incremental leaks much more …

OOP is pretty much has-been. Value semantics is the hot thing now I'd say.

Rather brassy claims. Your library has many issues. Some should be easy to fix. You missed many allocation/deallocation functions (3 from ISO C, 1 from POSIX and 4 non-standard one…

Valgrind (and the sanitizers) are only as good as your test coverage. Static analysis can cover all your code, though generally with a significant rate of false positives that you …

Are you trying to explain to me how Valgrind works? If you do know more than me then please join us and become a Valgrind developer. Mostly it wraps system calls and library calls.…

> Valgrind is a mock of standard library/OS functions and I think its existence is a good thing. That is mostly wrong. Valgrind wraps syscalls. For the most part it just checks the…

I agree that C is a basket case when it comes to safety and security. The CPU and the hardware don’t care how confident C coders are in their ability. C developers tend to forget t…

I do most of the Valgrind maintenance these days.

I wrote a series of articles for ACCU overload back around 2012 to 2013. This was in 6 parts. Introduction https://accu.org/journals/overload/20/108/floyd_1930/ Basic memcheck http…
