| Summary | 0002883: 100% reproducible crash when removing track outputs, possibly related to MIDI binding | ||||
| Description | i have one particular session that will crash whenever i try to remove an output in a track. it has a midi controller bound to the panner object. what i *think* happens is this: track has two outs and hence, an implicit stereo panner. midi controller was bound to panner. one out is removed. the stereo panner goes away. the dangling controller binding immediately causes a segfault. travelling atm, so i can't verify this hypothesis right now. comments welcome. | ||||

carl, a bt with line numbers (DEBUG=1) would be *perfect* :) |

here's one. it didn't immediately crash when i removed one output, probably because i had midi feedback disabled. touching the midi controller did it in, though.
