Recreatable Bug in Audition 3

Question

Hello all, I believe I have found a re-createable bug in AA3 and here is how you can create it.
Load up a session, and on one of the tracks select all the clips.
Now, right click a clip and select "clip envelopes > pan > use splines".  So now you have set the clip pan envelopes (NOT the volume envelopes but the PAN envelopes) to use splines.
Now play back your Multitrack session and within the clips you have set to use splines, keep creating new enveloping points and adjust these envelope points just before the cursor while the cursor is playing and moving toward the envelope points...adjust envelopes just before the cursor gets there and eventually Audition will stop functioning and you will get the message
"Microsoft Visual C++ Runtime Library
(X) Runtime Error!
C:\ProgramFiles\Adobe\AdobeAudition 3.0\Audition.exe
R6025 Pure Virtual Function Call"
It also happens (although not nearly as often) when I'm adjusting the "pan splines" whilst Audition is not playing the session, and is completely stopped.
This is the first real "bug" I have encountered, has anyone else had the same experience or are you able to re-create it?  You have to play with the splines from anywhere from 10 seconds to a minute and eventually with repeated changes in the pan and the addition of more envelope points it will crash.
Just wondering if anyone else has experienced this, or if you can re-create it in 3.0.1, which I have yet to upgrade to because my friend did and he has now encountered bugs that were not in the original 3.0, can anyone confirm this bug and/or whether it's been fixed in 3.0.1?
My system has been so stable otherwise I don't want to touch it, even with this re-createable bug, after it crashed if I "control+s" and save the results, it doesn't save the session permanently, but when I choose "continue session" in the post-crash dialog box, it returns my clips with the spline envelopes set just as they were just prior to the crash.

Could you possibly direct me to a list of what 3.0.1 corrects?
I can do slightly better than that - I'll post it here:
Changes in Adobe Audition 3.0.1:
• Spectral tools no longer crash machines with more than four CPU  cores.
• The Graphic Phase Shifter effect has been reenabled.
• Performance while recording MIDI data has been improved.
• The Sequencer will now record MIDI data even if the panel is  closed.
• Adobe Audition will now launch on Windows Vista® systems where the  My Documents folder was moved from the default location.
• The application will now ignore Windows "Locale" settings to  format decimal data in comma-delimited XML settings files.
• A Healing Brush crash issue has been addressed.
• Crossfades are no longer incorrectly added to grouped clips when  overlapped with non-grouped clips.
• Invalid crossfades will no longer be added to the end of a  previously trimmed clip after enabling or disabling looping.
• Invalid crossfades for clips after enabling non-session  tempo-based looping have been addressed.
• Dragging crossfaded clips onto the master track no longer creates  two additional tracks and an error in the crossfades. 
• Inserting MIDI from the Files panel would cause the application to  hang in Edit mode for an audio file whose sample rate didn't match the  session.
• Several scenarios where crossfade changes could corrupt a session  were addressed.
• Closing a session without exiting the rewire app no longer causes  Adobe Audition to save a blank session.
• Undo no longer becomes disabled after undoing the creation of  unique copies of two crossfaded clips.
• Crossfaded clips no longer disappear after undoing move clips.
• Canceling VST scan no longer causes Adobe Audition to become  unstable.
• If a selection existed, a full session mixdown would only process  MIDI data through the end of the selection.
• The Open MIDI dialog box was not completely modal and could cause a  crash.
• MIDI Host had problems with some Spectrasonics VSTi instruments,  where it wouldn't show the entire UI.
• CD burning would sometimes create a corrupted disk but still  report a successful burn.
• Applying the Clip/Pop Eliminator no longer crashes the  application.
• Crash recovery is now more reliable when using Auto-Save For  Recovery.
• When the application detects the possible saving failure that  causes a corrupted session, a warning dialog box now appears so users  can retry the save.
• Transport controls are no longer disabled if a new session is  opened without closing the existing session.
• Crossfades will now retain their original shape when clips are  moved and the session is reopened.
Please note the one I bolded, and the one underneath. I also strongly suspect that this is only the list of tangible things - there have been quite a few changes 'under the hood' to make all this possible, and this has definitely been more stable than the original version - I had healing brush crashes before, and not a single one since. I'm not aware of a single report from anybody that this bugfix release has made anything worse or more unstable at all, and most reports of crashes have more to do with people's unstable OS installs than anything else, and they certainly don't relate to the bugfix, whatever you may have heard.
