Logic crashes on startInternalDrag

[HISEnberg]

@Oli-Ullmann I reached out to Ableton last year for a NFR copy of Ableton 12 to test plugins and they were more than happy to accommodate me. Worth a shot ;)

@David-Healey
Both versions (AU and VST3) work in Reaper. So it seems to be a Logic issue. :-(
Any ideas?

@ulrik
Even with isDragOnly, Logic still crashes.

@ustk @HISEnberg
I saw that there's an affordable "Live 12 Intro" available. I'm going to buy it to give it a try. :-)

Can you recreate the issue in a minimal snippet?

[Oli Ullmann]

@David-Healey
Yes, I compiled @Christoph-Hart 's “Script Panel Drag Example,” and it crashes in Logic as well.

@Oli-Ullmann Does AUVal provide any insight?

[Oli Ullmann]

@David-Healey
Do you mean Tracktion's pluginval? I didn't get any errors with my plugin at the highest strictness level. But that might also be because the panels aren't visible when my plugin starts up.
I'll compile Christoph's snippet and test it with pluginval. I'll get back to you once I've done that.

pluginval

I think that only handles VST, I'm talking about AUVal which is included with macOS

Moonbase have a little article about it: https://moonbase.sh/articles/debugging-your-audio-unit-plugin-with-auval-aka-auvaltool/

[Oli Ullmann]

@David-Healey
You can also use pluginval to test AU plug-ins. According to your article, AUVal runs under the hood in that case.

I tested Christoph's snippet. No errors are reported here either. However, it also crashes in Logic. :-(

I get the feeling that I'll have to code the drag-and-drop functionality myself...

Ah that's good to know!

[ustk]

@Oli-Ullmann You can run pluginval as host in xcode (edit scheme -> Run -> Executable). Start the plugin as debug and see what it spits out

[Oli Ullmann]

@ustk
Oh, I'll have to check out how that works. Thanks for the tip! :-)
