[Bug-readline] rlwrap using readline-6.3 segfaults after pressing "r[PgUp][PgUp]" on Mageia Linux x86-64 6/Cauldron

[Shlomi Fish]

Hi all,

* readline-6.3 from source

* An Intel Core i3 machine running Mageia Linux x86-64 6/Cauldron.

* Building with:

./configure --prefix="$HOME/apps/readline-TO_DEL" --with-curses=yes \
--enable-multibyte

config.h attached.

* Running "rlwrap cat" and pressing r[PgUp][PgUp] causes rlwrap to crash. Also
see:

http://bugs.python.org/issue24958

* attached is a reproducing INPUTRC file.

The bt full is:
