            Bug ID: 59621
           Summary: wrong caret / lineno for wrong ctor field initializer
           Product: gcc
           Version: 4.8.2
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c++
          Assignee: unassigned at gcc dot gnu.org
          Reporter: jan.kratochvil at redhat dot com
                CC: dodji at gcc dot gnu.org
            Target: x86_64-unknown-linux-gnu

class C {
public:
  void *ap,*bp;
  C(int i,void *p):ap(i)
  ,bp(p)
  {}
};

g++ -c cxxctor.C -Wall -g

The error may be really confusing for many non-trivial ctor parameters.
