It would be nice if you could compile reiser4progs with debugging
symbols and then run it in gdb to get a backtrace:

$ apt-get source reiser4progs
$ sudo apt-get build-dep reiser4progs
$ cd reiser4progs-1.0.7
$ DEB_BUILD_OPTIONS="nostrip noopt debug" dpkg-buildpackage -b
$ sudo dpkg -i ../reiser4progs*.deb
$ sudo gdb fsck.reiser4
(gdb) r /dev/mapper/isw_jfcfihbei_RAID08
(gdb) bt
(gdb) quit

Even nicer would be if you would directly send it (and your other
comments above) to upstream at reiserfs-de...@vger.kernel.org, else I do
it for you.
List isn't subscriber only but you should state that you want to be CCed
if that's true.

This month there was a small thread that cryptocompress seems to be
stable but someone noted that it would be better to use tea hashing
instead of r5:
