Signalled while building preamble

I've attached the offending headers, but I can't share the relevant *.cpp file.

Should I move this issue to another repository? If so, which?

[headers](https://github.com/user-attachments/files/18613126/range.tar.gz), but I can't share the relevant *.cpp file.

Should I move this issue to another repository? If so, which?

Looks like there was a fix for something similar recently, if I can get a cutting-edge build of clangd out of Nix I'll give it a go.

And it looks like this fix for a similar problem (removing boost-use-ranges from clang-tidy) works for me too. does not work for me.

Yeah, that looks pretty similar based on the stack trace. If you're able to test the behaviour with a pre-release build of clangd 20 or trunk, please do so and update the issue with your findings. (Not sure how applicable it is to Nix, but two places I am aware of for finding pre-release clangd builds are weekly snapshot releases at https://github.com/clangd/clangd/releases, and packages at https://apt.llvm.org/.)

That's a different crash which was fixed in 19.1.2.
