Carbon in Cocoa Crashing: EXC_BAD_ACCESS after NSAutoreleasePool is released

Question

I'm developing a Cocoa user interface for a Photoshop CS3 plugin using Bindings. (Carbon in Cocoa, since PS is a Carbon app) I'm getting a EXC_BAD_ACCESS error when I close my modal NSWindowand the NSAutoreleasePool releases.
I've spent hours now with Instruments trying to figure out which object might be getting released early (or double released) and cannot find it.
Now my thoughts are that maybe there is something I'm missing about running a modal window within an NSAutoreleasePool while using Cocoa Bindings. Like maybe there is something I'm supposed to do before closing the window to "finalize" all the bindings to prevent them from sending messages to released objects.
Here is a basic code example of what I'm doing:
NSAutoreleasePool *localPool = [[NSAutoreleasePool alloc] init];   
NSApplicationLoad();
ExportWindowController *controller = [[ExportWindowController alloc] initWithWindowNibName:EXPORT_CONTROLLER_NIB_NAME];
[controller showWindow:nil];
[NSApp runModalForWindow:[controller window]];
[controller close];
[controller release];
[localPool release];
The modal window is closed by a call to:
[NSApp stopModal];
Here is a stack trace:

.... more
Turning on NSZombieEnabled did not turn up any double-released objects (although there was 1 from Photoshop itself)
Any ideas?

Answer 1

not using bindings seems to have fixed it, but if any of you have insights as to why this would be crashing with Bindings, I'd appreciate it.
Thanks
