When I start Emacs with

  ./src/emacs -Q src/print.c -f outline-minor-mode -f outline-hide-other --eval 
'(progn (pop-to-buffer "print.c") (while t (next-line) (redisplay)))'

it crashes like so:

  marker.c:331: Emacs fatal error: assertion failed: BUF_BEG_BYTE (b) <= 
bytepos && bytepos <= BUF_Z_BYTE (b)
  Fatal error 6: Aborted

The backtrace is attached.
