Please note that this message will contain a full copy of the comment thread, including the initial issue submission, for this request, not just the latest update. Category: puredata Group: v0.41.0 Status: Open Resolution: None Priority: 5 Private: No Submitted By: Nobody/Anonymous (nobody) Assigned to: Nobody/Anonymous (nobody) Summary: turning on DSP crashes PD (at least in Windows)

Initial Comment: When turning on DSP for the N-th time, PD sometimes crashes.

My empirical investigations lead me to think it happens when there are a big number of instances containing both [outlet]s and [outlet~]s

I attach 3 zip files containing 3 tests.

Each zip contains a main patch and the abstractions used within it.

Testing on PD Vanilla 0.40, Windows XP, Intel core duo.

*** A.ZIP ***

- Open the main patch "test_crash_dsp3_new.pd"

- Turn DSP on and off repeatedly. You can either do it manually or use the metro included in the patch.

-> PD will crash around the 48-th time you turn DSP on.

You don't need to switch "frenetically": I set the metro at a high rate to reach the crash in less time, but you can change it to [metro 1000] if you are willing to wait 96 seconds.

*** B.ZIP ***

- Open the main patch "dspcrash.pd"

- Turn DSP on and off repeatedly.

-> PD will crash around the 30-th time you turn DSP on; sometime much earlier, such as at the 8-th time.

*** C.ZIP ***

This is cleaner, but triggers the bug more unpredictably.

- Open the main patch "main.pd"

- Turn DSP on and off repeatedly

-> PD will crash at some time when turning DSP on. It may crash at the 10-th time you turn it on, or you may need to turn it on/off more than 500 times.
