API renderer crashes when using Jacko opcodes

[gogins]

Please see the Enable Jacko in blue issue for more information.

To test this, build and install the Jacko opcodes from my fork of the plugins repository.

Then load the attached blue_test.blue project in blue. hs_err_pid55016.log

On my Ubuntu Ubuntu 22.04.3 LTS amd64 machine, blue will run this project just fine when Render Method is set to "Commandline Runner", but immediately crashes with the attached crash report when Render Method is set to "Csound 6 API".

I wonder, is this because blue uses the API to call csoundPerformKsmps in a tight loop? That might not work here.
