Hm, I get this when I try it:

tmp $ cat main.c
int main(void)
{
        int x;
        ++++x;
}
tmp $ gcc -c main.c
main.c: In function ‘main’:
main.c:4:9: error: lvalue required as increment operand
    4 |         ++++x;
      |         ^~

I suppose it can be made to work with operator overloading. I will add a language check.

Ah, it is only allowed in C++.

It is also not handled by us - I filed https://trac.cppcheck.net/ticket/14920 about it.

CMake Error (install-absolute-destination) at cli/CMakeLists.txt:42 (install):
  INSTALL command given absolute DESTINATION path:

    C:/Program Files/Cppcheck/bin
This error is for project developers.  Use -Wno-error=author or
-Wno-error=install-absolute-destination to suppress it.

This is caused by a behavior change in CMake 4.4 (which is not rolled out on all runners yet).
