I dug a bit more and found that the IDLDE is crashing with the hw accel
OpenGL. I have to admit that I didn't suspect this, thinking that if
command line IDL worked with hw accel, then the IDLDE should too.
I'll submit a bug report to Apple. Hopefully they'll do another beta
release and this fix will be part of it. It turns out that this particular
problem is very similar to the first problem (in beta 0.1) that they fixed
that made command line IDL work. So, I have a feeling that they have a bit
more work to do in this area. All I can suggest is using software rendering
if you must use the IDLDE.
If anyone is interested, here is the stack trace from the crash log. The
line between frames 10 and 11 is the line between the IDL and the Apple
code. The DRI (Direct Rendering Infrastructure) is a mechanism for OpenGL
client programs that allows fast rendering on a local X server. In a "pure"
sense, the client program would encode OpenGL commands into GLX protocol,
send them to the server, which then decodes them and draws. This is
horribly inefficient, so the DRI exists to provide a direct path to the 3D
drawing code that runs in cooperation with the X server process.
So, if your IDLDE crashes and your log (in /Library/Logs/CrashReporter)
looks like this, then you know what is going on.
