With debugging information included, I get the following backtrace
Program received signal EXC_BAD_ACCESS, Could not access memory.

If I understand correctly, the problem is crash is in pager.cc in the lines
below.
362 void
363 flush_octave_stdout (void)
364 {
365 if (! flushing_output_to_pager)
366 {
367 unwind_protect::frame_id_t uwp_frame = unwind_protect::begin_frame ();
368
369 unwind_protect::protect_var (really_flush_to_pager);
370 unwind_protect::protect_var (flushing_output_to_pager);
371
372 really_flush_to_pager = true;
373 flushing_output_to_pager = true;
374
375 octave_stdout.flush ();
376
377 clear_external_pager ();
378
379 unwind_protect::run_frame (uwp_frame);
380 }
381 }
I have no idea is anything useful in this. Anyone?
