More than one question:

        You're welcome.

        + what was the date for the "last 5.9 patch"?

Last patch available last thursday on invisible-island.net. I don't remember its date, maybe ncurses-5.9-20150707.

        + what configure options did you use with "6.0"?
          (still pre-release, to check for regressions)

        Same options for both 5.9 and 6.0 :
configure --prefix=/usr/local --enable-static

        + "6.0" can be configured to be the "same" as 5.9 using this option:
          Did you try building ncurses with that?

Yes, and with --with-abi-version=5.9 --with-rel-version=5.9, readline runs like a charm.

        + what I recall of readline is that it does not use much of ncurses'
          screen optimization.  But I haven't looked at it for quite a while.
          You _might_ have to recompile it to work with "6.0".
          Did you do that?

        I have.

example, backpspace doesn't work anymore :

1: 1234

        All backspaces are printed as regular space even if 'azerty' string
is delete. Arrow keys doesn't work anymore as expected. If I link
the same program against ncurses 5.9, it runs like a charm.

        I don't understand interaction between ncurses and readline. My
program is statically linked against readline _and_ ncurses.

I'll have to investigate - simply have been short of time...
