Ways to generate crash dumps for crash handling?

Hi there!
I was interested in generating crash minidumps cross platform for debugging-- I've found them to be a useful tool for debugging. I know you can use SEH on Windows, but that's exclusive to windows, and cannot be mixed with C++ exception handling. Is there a way to write an exception handler that can grab what the state of memory looked like, as well as the call stack in order to generate a crash report/crash dump? I know there's also like google breakpad/crashpad but it seemed like I'd need to add in chromium to my project, and there's also Sentry, but I wanted to see what other options I have.

Performance Engineer or RL Engineer

Dear all, I have an experience in performance optimization. I have worked in this field for a few years. I also have experience in C++ for many years.
Now I got an offer in RL field in a big company. It is confident.

Experience in performance opens a lot of doors. I can work in many big-techs.
But ML is growing now. And LLM probably can remove doors for C++ engineers.

Should I change my direction? I'm 30 years old now.

UPD: RL is Reinforcement Learning

Do C++ developers exist?

Howdy folks! 🤠

I’ve been running an open-source project that turns images into colour-by-number templates. The JS side of things is doing great and I’ve got contributors for that, and they’re awesome.

Getting someone to touch the C++ core is like trying to find a unicorn. Seriously, it’s like C++ is the Black Plague to these people.🧟‍♂️ Everyone wants to work on the fun JS stuff, the frontend & React Hook WebAssembly bridge… but when it comes to the heavy-lifting C++, suddenly it’s “too hard” or “nah, I’ll pass.”

I get it, C++ can be a beast, but this is literally the heart of the project. Without it, none of the clustering or image processing magic even works. It’s like asking someone to play Jenga with bricks instead of sticks: still fun, but way more painful!

So here I am, ranting to the void. You're my last hope. Help me find the only other C++ developers on this earth.😁

If you know of someone who secretly enjoys fighting with C++ memory management and optimization, you are my hero. The JS folks are doing great, but we need some brave souls to dive into the C++ trenches with me so we can help the JS guys continue enjoying life.

Does anyone else feel this pain in OSS projects? Or am I just cursed to be the only one hunting for C++ contributors forever?

Possible GCC reflection error

Playing with GCC I got a situation like this:

#include <algorithm>
#include <array>
#include <print>
#include <meta>


consteval auto Name(const int integer){
    return std::meta::displaystringof(^^integer);
}
consteval auto Name(const std::meta::info meta){
    return std::meta::displaystringof(meta);
}
// <source>:21:28: error: call to consteval function 'Name(^^int)' is not a constant expression
//    17 |     std::println("{}", Name(^^int));
//       |                        ~~~~^~~~~~~
// But removing const fix it!! (works in Clang P2996)




int main(){
    std::println("{}", Name(3));
    std::println("{}", Name(^^int));


    return 0;
}

I think that this is not the expected behaviour, but is it a known bug to be patched?
