Waves plugins crash when reordered in Ardour

[ollyollyollyltd]

I'm having a problem where the Waves plugins are loading up fine, but any attempt to reorder them on their track / bus causes Ardour to crash.

This also happens if you attempt to bypass the plugins using the ardour bypass button (as opposed to any that the plugin itself provides), and if you just let the plugin run for a while (2 mins). I have included stack traces for a crash when reordering and a crash from general usage. These are traces from Ardour, I am not sure how to generate a trace from LinVST directly; though when I directled gdb at it's PID it reported it had shut down normally, as Ardour crashed. I'm not great with this stuff though so if you let me know of any other debugging I can do to help I will try!

This is occurring with the Vocal Rider and Bass Rider plugins. I have not tested any others as yet.

Until the crash the plugins do appear to be working correctly, and the signal is being processed as expected.

Environment

Ubuntu 19.04 LinVst-2.7-Debian-Stretch

$winetricks --version
20190912-next - sha256sum: fcb6abf715ffec36e4b0ac95ceea5ec16a22cb5158be0f6592ea629fc8ffd2e8

wine --version
wine-4.0 (Ubuntu 4.0-1)

Steps to reproduce

• Install Waves plugins using this guide https://blog.inagaki.in/en/linux-waves-plugins-en/ (basically the same info as presented in the LinVST detailed readme)
• Add 'Bass Rider Stereo' or 'Bass Rider Mono) to a bus
• Plugin loads of and GUI is displayed)
• Drag newly added plugin to new position in list on bus (e.g. from after fader to before

Expected behaviour

Plugin takes new place in list

Actual behaviour

• Ardour GUI freezes. Windows can still be moved around / switched but nothing can be clicked on
• If playing, playback continues for ~ 30-60 seconds
• Ardour crashes
• JACK server remains intact and reports Ardour disconnect

To my eye the issue is it trying access 0x0000000000000000 in threads 0 and 49 (reordering) and in thread 50 (general). But I don't really know what that means for me getting the plugins working :)

Thank you for your work on LinVST. This is very exciting!

[osxmidi]

It could be a lot of things.

I don't know how well Ardour supports shell plugins.

There are also overrides that might cause problems if you have them installed such as the overrides in this https://blog.inagaki.in/en/linux-waves-plugins-en/

I don't think it's a LinVst problem because as far as I'm aware I havn't seen the bypass and reordering problems with the plugins I've had running in Ardour.

Trying another daw to see what it does can be helpful.

Does the same thing happen with Reaper for instance which does support shell plugins.

There is also shell2vst which can extract the multiple plugins in a waveshell out to individual plugins which can then be wrapped which might produce different results as compared to wrapping the multiple plugin waveshell.

[ollyollyollyltd]

@osxmidi alrighty, thanks for that. When I get some time I'll have a fiddle around with and see what if I can get anything more specific.

Kind regards,
