VST3s in separate/dedicated process are able to crash Reaper to desktop (FIXED)

What the title says.

I have a trial version of a plugin that can reliably reproduce the issue if anyones interested but the reproduction steps are a bit tricky.

Sometimes the CTD occurs at the very moment the plugin crashes and sometimes it crashes when I try to switch the plugin offline/online after the plugin crashed for the first time.

The same plugin in *VST* (aka not VST3) version will not CTD Reaper when it crashes.

That's why I suspect Reaper not handling VST3s correctly.

I am happy to provide reproduction steps when asked by the devs, as they are time consuming and complicated.

Excuse my ignorance but what is CTD?

CTD = Crash To Desktop

Thanks for the reality check, I have updated the title.

Yes please provide the name of the plug-in and link to the trial download page, and steps to reproduce!

OK, here you go.

Please, see the dropbox link to download a zipped word file with reproduction steps and screenshots.

I was unable to upload it to this post as an attachment. For some reason it fails.

EDIT:

I have reuploaded the file at 17:27 CET. There was a missing step in it. Make sure you have the current version.

thanks, duplicated, looking into the cause of this (and asking Melda for help!)

You are the man, Justin!

Would be interested in more details as you progress if you have time but fixing the issue would be enough of course. ;-)

Best of luck!

Ah sounds like it's a Melda bug, they are fixing it now!

Kejnel · 08-29-2022, 07:28 AM

Hold on, Justin, I am not sure I follow.

I mean, isn't the whole point of the separate/dedicated process feature to prevent Reaper crashing *even if the plugin is buggy*?

Shouldn't this be considered an issue with the Reaper's crash-prevention feature as well?

Shouldn't the feature be improved so that no matter how buggy a VST3 plugin is it will not crash Reaper?

It's not like we have the Ableton Live's project recovery in Reaper that would made this a non-issue, right?

I can make a plenty of unrecoverable changes in the minimum one-minute interval of Reaper's auto-save function that would get lost because of this.

Thanks for consideration.

Justin · 08-30-2022, 08:39 AM

ah yes, that can be improved too, fixing

Kejnel · 08-30-2022, 11:53 AM

Excellent news, Justin! Thank you!
