Summary	0008650: Drumgizmo LV2 Crashes Ardour
Description	When loading the CrocellKit v1.1 (https://drumgizmo.org/wiki/doku.php?id=kits:crocellkit) from Drumgizmo v0.9.19, Ardour (6.6 official and 6.6.216-dbb nightly) crash. Loading the same kit with VST does not crash. Loading Tchackpoum DrumGizmo kit version 1.3 (https://drive.google.com/file/d/1s4w-rbumGvi5FYj61188vL_tpfPq3zXM/view?usp=sharing) with LV2 does not crash.
Steps To Reproduce	Create new session. Add MIDI track with drumgizmo LV2. Let it fan out to 16 tracks. Load CrocellKit.
Additional Information	Backtrace attached.

x42 2021-04-03 12:36 administrator ~0025671	The crash happens in the plugin. Likely nothing we can do on our end. It might be helpful to use a debug version of drumgizmo.

x42 2021-04-03 12:39 administrator ~0025672	notified upstream: https://www.drumgizmo.org/irc-logs/drumgizmo.log.2021_04_03

deva 2021-04-03 14:25 reporter ~0025673	Could it perhaps be a memory allocation issue? (CrocellKit is rather big) How much memory do you have in the system? Does it also happen if you limit the memory for the disk-streamer?

finotti 2021-04-03 14:29 reporter ~0025674	Thanks for looking into it! I don't think it is memory, as I have 32GB. Memory: RAM: total: 31.24 GiB used: 18.74 GiB (60.0%) Array-1: capacity: 32 GiB slots: 4 EC: None Device-1: ChannelA-DIMM0 size: 8 GiB speed: spec: 1600 MT/s actual: 1333 MT/s Device-2: ChannelA-DIMM1 size: 8 GiB speed: 1333 MT/s Device-3: ChannelB-DIMM0 size: 8 GiB speed: spec: 1600 MT/s actual: 1333 MT/s Device-4: ChannelB-DIMM1 size: 8 GiB speed: 1333 MT/s I am running the LVST with it right now. I also tried disk-streaming with LV2 and the CrocellKit and it crashed just the same. I've used this set up (DG LV2, and CrocellKit) many times in the past, but I hadn't used in probably the last 6 months... Let me know if I can provide any more details!

deva 2021-04-09 17:34 reporter ~0025687	Did you use the jack engine or alsa engine when experiencing the crash? Another user experienced a similar issue but only when using alsa, not jack.

finotti 2021-04-09 18:38 reporter ~0025688	Ah, yes, I was using alsa. I used to use jack, but I was running into some problem with MIDI and jack, so I started using alsa. That might be why it did not use to happen to me before.

finotti 2021-04-09 18:42 reporter ~0025690	Indeed, I just ran 4 tests, twice with jack and twice with alsa. Jack worked both times, alsa crashed both times.

deva 2021-04-09 19:45 reporter ~0025692	It may be due to a big stack allocation inside the setSamplerate function. Are by any chance running a 44k1Hz session with CrocellKit? Aka. with resampling enabled?

finotti 2021-04-09 20:02 reporter ~0025693	No, I'm using 48kHz sample rate.

deva 2021-04-09 21:09 reporter ~0025694	If you are able to compile drumgizmo from sources, you could try changing src/drumgizmo.cc line 476 from sample_t s[sz]; to static sample_t s[sz]; that might fix the issue.

x42 2021-04-09 22:20 administrator ~0025695	Ardour 6.6-250-gbc1d19ab39 also solves this -- tncreasing available stack size to the same limit that jack2 has.

x42 2021-04-09 22:22 administrator ~0025696	Fixed in Ardour 6.6-250 Also per IRC discussion drumgizmo has further work scheduled to mitigate the issue.

finotti 2021-04-09 22:24 reporter ~0025697	Thanks to both of you for your hard work and great support! (And for the great software!)
