[Bug tree-optimization/38997] New: -ftree-loop-distribution ICEs

[kazu at gcc dot gnu dot org]

Consider:

char a[8][8];
char b[8];

void
foo (int i)
{
  int j;
  for (j = 0; j < 8; j++)
    {
      a[i][j] = 0;
      b[j] = j;
    }
}

I get:

$ ./cc1 -quiet -O2 -ftree-loop-distribution min.c
min.c: In function 'foo':
min.c:5: internal compiler error: in build2_stat, at tree.c:3298
