With --clang, Cppcheck seems to crash on a file as minimal as:
main(){}
Here is my gdb session from version 2.1-1:

I do have Clang+LLVM 10 installed. The Cppcheck package doesn't hint to
install Clang, so please add Suggests: clang.
In a fresh snapshot.debian.org (20200531T211512Z) chroot, I've
found this crash also happens with 2.0-3. The version in Buster doesn't have
the --clang option. The crash does not happen if Clang is not installed.
