When I run ensemble_chorus_fl, I get the following output:

[2]    3630 segmentation fault (core dumped)  ensemble_chorus_fl

jpcima commented 4 years ago

Since it dumps core, would you be able to extract a backtrace from it? (on Debug or RelWithDebInfo build)

eg. coredumpctl debug and then bt

Are you able to reproduce this backtrace on a debug builds, symbols not stripped ? -DCMAKE_BUILD_TYPE=Debug in cmake

also which Jack version is it?

magnetophon commented 4 years ago

Hmmm, looks the same to me. Maybe I did it wrong, or maybe it's just cause NixOS is a bit odd.
