Hi!
Here is a minimal reproducer if someone needs regression test.

typedef struct fibnode
{
  struct fibnode *parent;
  __extension__ unsigned long int degree : 31;
  __extension__ unsigned long int mark : 1;
} *fibnode_t;


void fibheap_cut (fibnode_t, fibnode_t);
void fibheap_cascading_cut (fibnode_t);

void
fibheap_cascading_cut (fibnode_t y)
{
  fibnode_t z;
  while ((z = y->parent) != 0)
    {
      if (y->mark == 0)
        {
          y->mark = 1;
          return;
        }
      else
        {
          fibheap_cut (y, z);
          y = z;
        }
    }
}
