| Summary | 0010447: OSC /set_surface with feedback bit 16 (Master Section) crashes Ardour at surface registration | ||||
| Description | Enabling feedback bit 16 (Master Section) in an OSC /set_surface call crashes Ardour immediately upon a client registering with that feedback value. Findings via /set_surface sent from a fresh Ardour instance each time: - strip_types=21, feedback=8 (heartbeat only) — stable - feedback=75 (+ strip buttons/controls, timecode) — stable - feedback=91 (+ master section, bit 16) — crashes - feedback=203 (= 219 minus bit 16) — stable (Session has the monitor section enabled.) | ||||
| Steps To Reproduce | 'oscsend localhost 3819 /set_surface iiiiii 0 21 91 0 0 0' sent to a freshly-started Ardour with OSC control surface enabled (Preferences -> Control Surfaces -> OSC), Port Mode Manual, any reply port. | ||||
| Additional Information | Video demo: https://youtu.be/zZI655452vA Backtrace attached. | ||||
