Here is the callback with -v and warnings suppressed. Here it is without warnings suppressed. But I don’t believe that they are causing the issue. Here is the code.

How can “plugins” loaded by libdl refer to symbols in the program which loaded them?
Imagine that you have an application with a plugin based architecture, where each plugin is a *.so file that is dynamically loaded with dlopen(). The main application can refer to symbols via dlsym(), and so it may call functions of the plugin. How can the plugin call functions of the main application? I know that the main application could provide
