Even more compact testcase:

========================================
int foo();

void bar()
{
  int i, j, k, *p;

  while (i)
    while (k)
    {
      for (i = 0; i < 5; i++)
        for (; p; ++p)
          for (j = 0; j < k; j++)
            switch (k)
            {
              case 1:
                ++k;
              case 2:
                break;
              case 3:
                ++k;
              case 4:
                ++k;
              case 5:
                ++k;
              default:
                k = foo();
            }

      if (j) break;
    }
}
========================================
