Opening carla session with Cardinal instance segfaults carla #21

Closed dromer closed 2 years ago

dromer commented 2 years ago

Tested with: lv2, vst2 and vst3

falkTX commented 2 years ago

mine seems fine, only got to 1 situation once where it was crashing so most of the time it works?

dromer commented 2 years ago

You make a cardinal patch. save the carla session. close carla. then open carla. open the carla session ->works ?

This is with latest carla git kx package on debian 11 with pipewire.

falkTX commented 2 years ago

Yes, that works fine here. Using the VST2 version mostly, as that is easier for the drag&drop.

Time to build in debug mode :)

Or use the prebuilt binaries.

falkTX commented 2 years ago

Cant reproduce this at all, even with lv2 version

CarloCattano commented 2 years ago

I have the same behavior on debian here. No way to open a carla saved project with Cardinal in it, it directly crashes as explained. Running with jack

falkTX commented 2 years ago

Can you share a carla project file that causes this? Thanks.

CarloCattano commented 2 years ago

Nevermind , Apparently it was happening with older carla project files that I overwritten with the vcv added to it . If I start a Carla patch from scratch and add vcv Im able indeed to load as expected . Maybe the case accidentaly for @dromer ? This is the patch where I added vcv to that crashes it fx_rack.zip But as I said , it could be totally unrelated , and otherwise works as expected

bloated.zip

Just tried with 3 instances . All plugins are there and the parameters(carla GUI macros) are as I left them too . Did not try with a heavy processing patch yet

falkTX commented 2 years ago

Should be fixed in 9ff29396dfe8ecc3cce748a474fd9af76cbbbb1c Testing would be appreciated.

This likely breaks Windows builds, will fix that later.

falkTX commented 2 years ago

Been testing/using this quite a bit in both Carla and testing on FLStudio. No more crashes since that commit, so going to assume fixed unless someone says otherwise.
