[Bug tree-optimization/25481] New: Segfault in tree-ssa-structalias.c

[kazu at gcc dot gnu dot org]

Compiling the following test case with "./cc1 -O2" ends up causing a segfault.

struct s {
  int *blah;
};

static struct s array[] = {
  { 0 }
};

void
foo (struct s *p)
{
  unsigned int n = 1;
  struct s *q = &array[n];
  while (p < q)
    p++;
}
