Segmentation Fault when booting SuperCollider Server.local with ZamTube installed #78

Closed scottericpetersen closed 4 years ago

scottericpetersen commented 4 years ago

Hi there - attempting to boot the audio server (Server.local) in SuperCollider 3.10.3 built from source on KDE Neon produces aprox. ~8500 errors of the like posted below, all while scanning the ZamTube-ladpsa.so plugin. The result is a segmentation fault. I got the plugin from KXstudio who packaged it as part of the meta-audio-plugins-ladspa collection. When I remove that plugin the server boots correctly. I have posted part of the output below.

Can you please find the source repo that was used for the plugin? I assume it contains an outdated version of my plugin. Please buy the real one on http://zamaudio.com, or compile it from this repo which is the upstream source code.

@scacinto This was my bug. Fixed in 87fdee6e87dbee75c1088e2327ea59c1ab1522e4 (Version 3.12)

Hi there - Sorry I was out of touch - end of the semester here in the US and I was neck-deep. Happy you found the problem!

Cheers,
