In map_groups__find_symbol() map->map_ip is used without ensuring the map is loaded. Then the address passed to map->map_ip isn't mapped at the first time. E.g. below code always fails to get a symbol at the first call; addr = /* Somewhere in the kernel text */ symbol_conf.try_vmlinux_path = true; symbol__init(); host_machine = machine__new_host(); sym = machine__find_kernel_function(host_machine, addr, NULL, NULL); /* Note that machine__find_kernel_function calls map_groups__find_symbol */ This ensures it by calling map__load before using it in map_groups__find_symbol().
