Summary: Tunring on DSP crashes PD
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.
