Occasional segfault. about helm HOT 5 CLOSED

Damn, these are the worst. I thought I fixed all the crashes.
I don't have a great way to track this down right now. I'll need to put in some logs and save the backtrace in a file when it crashes.

Before I do that, do you remember what you were doing when it crashed? Did you have automation enabled? Did you have more than one instance of Helm? Any information like that would help.

from helm.

I had no (external) automation, and 4 lv2 instances running.
Sorry, I can't remember any other specifics.

I have a kind of reproducible segfault with renoise + helm vst, it brings down everything.
@mtytel if needed I can share the xrns in private so that you can try to reproduce. (it does not happen always)
I am running under debian.

Also I have another issue. When I open a new renoise song, helm is silent even if it's receiving notes. If I load it again with my saved instrument it works

I do not know if this matters:

The _EvenProc part

I just had a segfault as well.
I was just playing with the standalone version, launched from the CLI, using JACK and a MIDI keyboard. I was testing different presets and at one point, helm become silent. I closed it, I tried to relaunch it but I had the segfault. I started it again from another terminal, and it worked great. I closed it, and retried from the terminal I launched helm first (when it became silent) and it segfaulted.
(running debian jessie updated and helm 0.8.6 from GIT)
Hope that helps.

I've fixed a few couple segfaults/silences regarding initial values (crashed on startup, silence on startup, etc), step sequencer (crashed when modulating) and some other GUI and modulation problems.

Since this issue doesn't have a repro that narrows it down to any of these specifically. We can reopen or file news issues when the next version (0.9) is out.
