> In code generated by the compiler for C (GLib), a service's processor class incorrectly treats function and void pointers as interchangeable: When adding to the {{process_map}} hash table it supplies a pointer to a function, while {{g_hash_table_insert}} expects a {{gpointer}} (effectively {{void *}}) to a data object.
> ISO C explicitly forbids this conversion as it is not compatible with all architectures, and with its {{-pedantic}} option enabled gcc will generate warnings like
> {code}
> gen-c_glib/calculator.c: In function 'calculator_processor_init':
> gen-c_glib/calculator.c:1231:24: warning: ISO C forbids passing argument 3 of 'g_hash_table_insert' between function pointer and 'void *' [-Wpedantic]
>                         calculator_processor_process_ping);
> {code}
> The compiler needs to be fixed so the code it generates does not try to use function pointers where data (void) pointers are expected.
