        <pre>It works fine if there is only one nested block:

int main()
{
    {
        {
            int a = 0;
        }
    }
}

But if we copy the code in the main function again, like this

int main()
{
    {
        {
            int a = 0;
        }
    }
    {
        {
            int a = 0;
        }
    }
}

clang-format will format the code above like this:

int main()
{
    {{int a = 0;
}
}
{
    {
        int a = 0;
    }
}
}
