Any estimation of the length of output that is needed to have a crash?
Also, would just "type LARGE_SOME_FILE" do, for example?

This doesn't make any sense.  Maybe again some snafu with frame
dimensions?

Please type "source .gdbinit" (unless you started GDB from a directory
where that file lives), and then go to this frame:

  #4  0x012125ec in display_line (it=0x82c890) at xdisp.c:19369

and type these commands:

  (gdb) pit
  (gdb) print *it->w
  (gdb) pmtxrows it->w->current_matrix
