I emailed support@rsinc.com, and they replied:
Please, rename the gl_driver.so, located in the idl/bin/bin.linix.x86
directory to gl_driver.old. This will force your system to software
rendering.
I don't know what it means, but it worked. I wish it was put in the
installation instructions.

I believe you mean ION rather than the IDL-Java Bridge.

Once upon a time, I had a successful IDL 5.5 installation on RH9. I
moved up to IDL 6.0 at the same time I upgraded the machine to Fedora
Core 1. So, I have never tried IDL 6.0 on RH9. But there's nothing
that makes me think that the IDL 6.0/RH 9.0 combination *should* cause
problems.
Do you get any core file when it segfaults? If so, you can try running
gdb on it and see if you can at least determine the library that the
fault is occurring in. That might help narrow your search. Good luck.
FWIW, I have glibc-2.3.2-101.1 installed.

IIRC you only get asked that if you try to install the IDL/Java bridge.

It works here. I've not done much testing on RH9, but it certainly starts
and I can do very simple plots.
I'm using stock RH9 which has glibc-2.3.2-11.9 - how did you end up with a
different (earlier) version? IDL was downloaded from RSI, installed on our
IRIX server, and the disk exported to the RH machine.

IDL can render images by using the graphics card itself or purely within
software. Using hardware rendering is faster, but certain graphics
cards don't have the necessary support in their drivers. Software
rendering is much slower, but it is supported everywhere.
Depending on the graphics card you have, see if you can find an
updated/better driver online. Some Linux distributions don't ship with
the actual company provided driver because of licensing issues, so you
might just have a general purpose driver.
There's a little more information here:
http://www.rsinc.com/services/techtip.asp?ttid=3524
Finally, I am not a fan of moving the shared object to force software
rendering. I've seen this kind of recommendation come from RSI before
with other issues, but changes like this should be made in configuration
files rather than moving libraries out of their standard locations. I
suppose it's a little pet peeve of mine since I come from the software
development ranks. Anyway, I believe you can set IDL to always use
software rendering by adding the line
Idl.renderer = 1
to either your ~/.Xdefaults file or to the system-wide
$RSI_DIR/idl/resource/X11/lib/app-defaults/Idl configuration file.
Just another way to skin a cat.
