I build lmms-1.2 on Fedora 30.

gcc version: 9.1.1

It looks like Fedora provides the development version of Carla instead of the stable version. There are some API/ABI breaking changes in the development branch, I think you should contact the Fedora package manager or manually build the stable version of Carla.
We hope we can support both versions, but it doesn't look that simple.

Good catch ...
I close the bug report :)
