            Bug ID: 48659
           Summary: clang-format splits function pointer in half
           Product: clang
           Version: 11.0
          Hardware: PC
                OS: Windows NT
            Status: NEW
          Severity: enhancement
          Priority: P
         Component: Formatter
          Assignee: unassignedclangbugs at nondot.org
          Reporter: barry.revzin at gmail.com

Here is a complete header:

template <typename R, typename... Args>
struct C { 
    R (*invoker)(void*, Args&&...);
};

which formats as:

$ clang-format wat.h 
template <typename R, typename... Args>
struct C {
    R (*invoker)
    (void*, Args&&...);
};

That should definitely stay on one line. 

My current .clang-format is:
