clang-format-20 was terminated by OOM-killer while formatting large c-header

system and version:
```
$ clang-format --version
Ubuntu clang-format version 20.1.8 (++20250708082409+6fb913d3e2ec-1~exp1~20250708202428.132)

$ uname -a

```

file size:
```
$ ls -lah ./drv_cfg.h
-rwxrwxr-x 1 tester tester 141K nov 17 12:43 ./drv_cfg.h
```

Memory usage increases every second until the system finally freezes/crashes:
```
$ while :; do ps -aux | rg clang-format ; sleep 1; clear; done
tester 6106 101 75.8 14380988 12239548 pts/0 R+ 12:46 0:20 clang-format-20 -verbose -i ./drv_cfg.h

```
The "-verbose" flag does not output errors to the console when formatting this file.

Can you make patch for 20th version of clang-format to fix this?
