If you can still reproduce it, show me the backtrace from
signal_or_quit when the buffer is scrolled from EOB to BOB.  That
backtrace should tell us which code still needs to be fixed.

That is, set a breakpoint in signal_or_quit with the following
commands:

  backtrace
  print current_buffer->pt
  continue
  end

then run your recipe and press C-g until you see the problem happen.
Then post the last few backtraces here.

I can no longer reproduce the problem on my system, so I cannot do
this myself.
