Here are the files that it requested to have attached:
[robot_body_filter-f711bb.cpp](https://github.com/user-attachments/files/25500150/robot_body_filter-f711bb.cpp)
[robot_body_filter-f711bb.sh](https://github.com/user-attachments/files/25500154/robot_body_filter-f711bb.sh)
also, if you're using nix and wish to reproduce it with the exact environment, I've attached a tarball of the project which should allow you to do that. However, I'm unable to reproduce this after the first time I encountered it. (also included is the full log from the compilation which failed):
[llvm-lexing-crash.tar.gz](https://github.com/user-attachments/files/25500351/llvm-lexing-crash.tar.gz)
I am running the build with the following command:
```bash
colcon build --mixin compile-commands mold clang ninja rel-with-deb-info --symlink-install
```
