I think we'll no longer activate thread_db when debugging core files of static executables (e.g., a core of gdb.threads/staticthreads). It works with live debugging since we call check_for_thread_db from linux_child_post_attach/linux_child_post_startup_inferior. Maybe moving that to an inferior_created observer in linux-thread-db.c would work. -- Pedro Alves
