I fondly remember one project that I inherited.  One bug was caused by some
code like this:

wait_for_esc()
{
  int ch;
  ch = 0;
  while (ch!=27)
    ch=get_key();
  return 0;
}

The bug?  Declaring ch as a local.

No function had a declared return type.  The ones that should have been
void just returned 0.  get_key() was one of them.  It put the key it read
into the global ch.
