ARAPluginDemo crashes in Logic

Audio Plugins
1
  • Build the ARAPluginDemo example on latest develop (793df5dd3d4368bc121c960b89b922e2ccae4fe2)
  • Open Logic (tested on 10.7.6 and 10.7.7 in Rosetta/Intel on macOS 12.5 on M2 MBA) and open a project in it
  • Add the ARAPluginDemo as ARA on a couple of tracks
  • Close the plugin UI
  • Hit play
  • Quit while still playing. I get the following crash (repro 2/2 attempts):

It appears that adding the following to ARAPluginDemo.h:EditorRenderer fixes the above issue:

    void willDestroyRegionSequence (ARARegionSequence* rs) override
    {
        regionSequences.erase (rs);
        rs->removeListener (this);
    }

However it appears that with the fix there are still more issues when enabling Thread Sanitizer with same steps to repro:

Even easier repro with Address Sanitizer (on latest develop 8ed3618e12230):

  • Debug Logic with Xcode with Address Sanitizer enabled (note that for plugin scanning to succeed it first needs to be ran without asan)
  • Add ARAPluginDemo as an ARA plugin to a track
  • Hit play (Logic workaround, otherwise it’s not really added…) and then stop
  • Quit Logic
