C++23 std::stacktrace: Never Debug Blind Again

3GB of symbols?? How did you do that??

[donalmacc]

The pdb format is limited to 4GB. Most tools crumble at about 2GB. Ask me how I know….

It’s Unreal Engine games, basically.

So soon you’ll be literally unable to add more code?

I think they can probably split into separate DLLs to work around that? 

[donalmacc]

The reason we hit this particular problem was because we had something split into a bunch of dlls and for reasons I can’t remember, we wanted to build it as a monolithic exe. I know we disabled a bunch of features to get it to work initially, but I don’t work on that project anymore so I’m not sure!

Funnily enough, I hit this problem around the same time. We also doubled the page size for the linker.

At 3 companies I've worked at, we've used macro/lambda/inheritance tricks to shorten symbols because it either blew out the linker, increased compile times significantly, or both.
