rvplayer crashes with a segmentation fault under RedHat.
Here's one workaround which may prove helpful for running
other Linux binaries which crash under glibc 2.0.108 and for
which source is not available:

* Copy these files from glibc-2.0.7 into /cpt:

ld-2.0.7.so         libc.so.6           libm-2.0.7.so
libresolv.so.2
ld-linux.so.2       libdl-2.0.7.so      libm.so.6
libc-2.0.7.so       libdl.so.2          libresolv-2.0.7.so

* Rename rvplayer to rvplayer.bin and make this shell script
named rvplayer:

#!/bin/sh
LD_LIBRARY_PATH=/cpt:/usr/lib/Real
export LD_LIBRARY_PATH
/usr/bin/rvplayer.bin $*

* Edit rvplayer.bin (with, e.g. emacs) and change the
reference to /lib/ld-linux.so.2 into /cpt/ld-linux.so.2

If you have a better workaround, or ideally, can fix the
compatibility code in glibc-2.0.108, please let me know.
