            Bug ID: 24432
           Summary: Too much information printed in macro diagnostic
                    message (binary operator)
           Product: clang
           Version: trunk
          Hardware: PC
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P
         Component: Frontend
          Assignee: unassignedclangbugs at nondot.org
          Reporter: zhengkai at google.com
                CC: llvm-bugs at lists.llvm.org

    Classification: Unclassified

#define SELF(x) x
#define APPLY(f,x,y) x SELF(f) y

struct node {
};

node ff;

int r = APPLY(+,ff,1);

Output is:
:69:15: error: invalid operands to binary expression ('node' and 'int')
int r = APPLY(+,ff,1);
              ^ ~~ ~
:61:29: note: expanded from macro 'APPLY'
#define APPLY(f,x,y) x SELF(f) y
                            ^
:60:17: note: expanded from macro 'SELF'
#define SELF(x) x
                ^

At least the last macro expansion should not be printed.
And whether the APPLY macro should be printed remains a question.
