Segmentation Fault pressing "Play" Button.

[Cordoha]

Ubuntu 16.04 Latest Dev version of RACK

I have the latest build of Bidoo running, I hit the play button about 5 times or so, and VCV Rack does a segmentation fault, it is reproducible. Not sure if it's Rack, or Bidoo, or if you're aware of the issue. Here's the output of make debug:

Mmm is it a patch containing a dTrOY instance you made before 0.5.14 ? When you write "I hit the play button about 5 times" .. which play button ? Is it a jump button on MOiRE or somethink else ? Please tell me more so I can help you.

[phdsg]

looks like dtroy from the logs. couldn't replicate (hammering away on the play button) on my linux machine.

edit: looking again at the log i see a hot tuna there. maybe it's this: https://github.com/nysthi/nysthi/issues/17

[sebastien-bouffier]

Haaaaaa, ok, the play button ... on dTrOY .. sorry but for me it is Play Mode so I was searching for a play button in Rack ... pffff .. I should go to bed. I did not managed to replicate too. Looking at the log I see that there is something about std distrib which is used by dTrOY in random play mode. I check.

Made several tests, stress tests and cannot replicate. Can you share your patch please ? Do you use Monome ? This plugin use std distrib too ...

[Cordoha]

My patch did change, and now I can't replicate. Weird. Sorry.
