[Bug tree-optimization/22373] New: loop linear produces type mis-match

[pinskia at gcc dot gnu dot org]

Testcase:
double u[1782225];
int foo(int N, int *res)
{
  unsigned int i, j;
  double sum = 0;
      for (i = 0; i < N; i++)
        {
          for (j = 0; j < N; j++)
            {
              sum = sum + u[i + 1335 * j];
            }
        }
      *res = sum + N;
}

Patch in PR 22368 finds this.
ltrans-3.c: In function 'foo':
ltrans-3.c:6: error: statement types mismatch
lletmp.14D.1311_31 = 0;
