Reduced testcase:

int a, b, c, d, e, f;

void
foo (int x)
{
  e = 1;
  for (;;)
    {
      int g = c;
      if (x)
    {
      if (e)
        continue;
      while (a)
        --f;
    }
      else
    for (b = 5; b; b--)
      {
        d = g;
        g = 0 == d;
      }
      if (!g)
    x = 0;
    }
}
