This is expected, and I tried to explain it in my message; sorry if I
was unclear.  The bidi Emacs is not ready to be a useful editor yet,
it crashes very soon after you turn on the default-enable-bidi-display
flag.  I think this will happen even if you don't insert any
character; just visiting a file with characters that require
reordering should be enough.

Please consider debugging the current code to fix the bugs.

The code in bidi.c where it crashes was written by me, so I should be
able to help you figure out what's wrong.  Unfortunately, I don't
have time to debug it myself; that's why I asked for help here.
