            Bug ID: 60257
           Summary: Incorrect column number and confusing message in
                    -Woverride-init
           Product: gcc
           Version: 4.9.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c
          Assignee: unassigned at gcc dot gnu.org
          Reporter: chengniansun at gmail dot com

I have two questions regarding -Woverride-init, 
1) the column number seems not right
        always starting from the beginning of the statement. 
2) the second message is confusing to me.
        is it trying to pinpoint the location where the field is first
initialized, similar to what Clang does?  


$: cat s.c
struct S {int i; int j;};
struct S s = {
  .j=4, .i=5, .i=6,
};
$: gcc-trunk -std=c99 -c -Woverride-init s.c
s.c:3:3: warning: initialized field overwritten [-Woverride-init]
   .j=4, .i=5, .i=6,
   ^
