Looking at,
it seems you're subclassing Genode::Thread and (presumably) instantiating it using the Genode thread API.

Others will correct me if I'm wrong but I think as of Genode 19.x it's no longer possible to call the LibC from such "pure native" threads.

You'll have to use the POSIX API instead (pthread_create() etc), and threads created in such a context will correctly register themselves in and no longer trigger the assert() in pthread_self(), in the ubiquitous errno handling and so on.
