This is the error when trying to activate the plugin:

Thanks for the report, and thanks for the logs. (BTW if you enclose the text in a pair of triple backticks, it'll display a little more sanely).

Do you know if earlier versions verify correctly? It'd be helpful if we could pinpoint what version introduced the issue.

[ServusJon]

Tested with:
Version 0.5.6
Version 0.5.8

same results :(

[sdatkinson]

Well, that's unfortunate. It's tough at the moment for me to figure out what's going wrong because the VST3TestPluginHost doesn't seem to show the corresponding failures in what seem to be the most similar unit tests that it runs with the (VST3) plugin.

I'm also had a little bit of a loss to figure out how to get more information about on this myself since I don't own Logic. Is there any way that you can get a more detailed output about what specifically is going wrong? I know that I've seen more complete-looking core dumps when even the release plug-in segfaulted on me in the past...

One other question: do you know whether the plug-in is being tested in the state it initializes into, or do you have the chance to eg pick a model before the validation that's failing gets run? I'm assuming no but just checking in case... Anything to try and figure out where to narrow my focus.

[ServusJon]

With the other versions I only tested the standalone versions. They had some really loud buzzing almost like a synth (saw) when playing. I selected different profiles...

[ServusJon]

also it crashed a few times as well

[ServusJon]

somehow its working now

[sdatkinson]

...huh! Mysterious...guess I'll keep my ears open if anyone else reports anything similar.
