Hi,
I get a segmentation fault when trying to run clang-format on a specific file.
- I installed clang-format-18 using `apt install`.
- I am running Debian 11 (bullseye)
Below is a stack dump:
```
Stack dump:
0. Program arguments: clang-format -i -style=file app/ultrasound_task.c -Werror --ferror-limit=1
Stack dump without symbol names (ensure you have llvm-symbolizer in your PATH or set the environment var `LLVM_SYMBOLIZER_PATH` to point to it):

Attached is the file that caused the seg fault (I renamed it to txt, but it was originally a c file). Let me know if you need more debug information.
