[Csnd] Possible bug in zak opcodes

The Csound Mailinglist

Hi all,

I believe there is a possible bug in the zack opcodes. Some old orc/sco combos that I have that have worked for years (and employ the zak opcodes) appear to now cause defaults in csound. I figured this out via educated guessing and got lucky when I disabled them.

Are there any recent changes in the codebase that come to mind, devs, that would cause this? (I have not looked at a git blame for the zak code).

They are deprecated in favor of the chn opcodes, right? And one always has global variables…but it is a shame, b/c I had quite a few orchestra built on piping things through Zzak that I would have to refactor…sigh.

Do you have an example that causes issues? And what version of Csound
and OS are you using?

Yes, I will provide an example after my workday…

OS is Linux (Mint; ubuntu-based)
Csound was 6.something (latest stable), and prior versions of 6…will get you specifics (AFK now)

I meant “segfaults”, not “defaults” in my first message. My phone auto-corrected I think.

Thanks, can you open a ticket when you have the example so we can track it there?
