I see you're on a MAC, so I'll try this when I get home from work, but just to know more about it, in what circumstances did it crash, whas it on opening a patch that contained a Clocked instance, or when adding one to a new patch, or something else? For me to have a chance to reproduce it, I would need more context please.

From the log, I can't see how it could be a problem with Clocked, because the crash occurs upon loading an SVG (probably for a knob or the panel or something), and that's all straight forward code that's been there for years. I'm keeping an open mind as always, it's just a bit puzzling and not clear what may be wrong here.

Hi Marc,

Sorry for the lack of detail. Yes - crashing upon opening a patch that contained a Clocked instance.

[MarcBoule]

Would it be possible to send me the patch (or a minimal one that has the crash)? That would really go a long way for me to help find the cause.

[pgatt]

Sorry, I hadn't saved the patch and I needed to debug some other issues. Close for now if you like, and I can re-open if I see it again.

[MarcBoule]

Ok, I'll mess with a patch on my Mac and see if I can spot anything, but yes, please re-open if you can get it again. Thanks!

[pgatt]

Okay, can reliably reproduce now. Here's how: Running Clocked clock out into the Randomize of Stöermelder Strip input and then quitting while the clock is running means that Rack crashes when reopening.

Ah, that is clearer. I managed to get a crashing log.txt this time, and it looks like Strip is to blame. log.txt

Good to know!
