Hello Bill,
Thanks for the feedback. The auval tool does show a small memory leak
in the FilterDemo, but not any immediately useful info about the
source. I will keep investigating.
I was thinking more of using these techniques when you are launching
AULab to see where the memory problems are coming from there.
I feel like we're missing something extremely fundamental here. How
are other people getting started in AU development, when the sample
code from Apple doesn't seem to be stable? This is a genuine question
-- not trying to be crass. This crash occurs on multiple machines, so
I'm pretty confident it is not "user error". Is there a better
example we should be working from?
Please file a radar report and we'll look into it. http://bugreporter.apple.com
Thanks

Here's a specific recipe for what I'm doing:
1. Build the Development config of the FilterDemo from the v1.4.3 SDK
2. Start AU Lab or Logic.
3. Create a new 44.1k project/session.
4. Insert 3 FilterDemo plugins.
5. Make their UIs visible.
6. Save the project.
7. Close the project.
8. Open the previously saved project.
9. Goto step 7.
The crash will occur within a handful of reloads, if not immediately.
Thanks,

Likely some memory scribbler...
Try running AULab with the guard malloc and scribble options and see
if that comes up with anything. The read me for AU Validation has
some
notes about this

Hello,
The FilterDemo AudioUnit often crashes when used in Logic v8.0 (and
v8.0.1) on both PPC and x86. This happens when a Project is
reloaded
that contains a few visible plugins. Here is sample call stack.
The
underlying orientation is often different, but always occurs in the
NotificationPost bit.
