[Bug c++/26997] New: g++ reports incorrect error message when the identifier with error occurs earlier on the same line

["pavel dot petrovic at gmail dot com" <gcc-bugzilla at gcc dot gnu dot org>]

The program below reports the following compiler errors:

bug.cpp:17: error: expected primary-expression before '*' token
bug.cpp:17: error: expected primary-expression before ')' token
bug.cpp:17: error: expected `;' before 'malloc'

which seem to refer to the first occurence of identifier "t"
on the line 17. However, that is a correct occurence.
The mistake is later on the line, but the error message
of the compiler is misleading. This is not a serious issue...

$ uname -a

$ g++ --version

-------------------------------------------
#include <stdlib.h>

typedef struct { int a; int b; } t;

int main()
{
  t v1, *v2;
  t *v3;

  v2 = &v1;
  v1.a = 2;

// correct code:
//v3 = (t *)malloc(sizeof(t) * v2->a);

// code with a mistake:
  v3 = (t *)malloc(sizeof(t) * t->a);

  return 0;
}
