Mam skompilowany program C z jednymgcc test.c lubclang test.c:

int main (void) {
    return 0;
}

valgrind ./a.out daje mi to:

GCC wersja 4.7.1 i wersja Clang 3.1. Co się z tym dzieje? Czy coś jest nie tak z moją pamięcią? Od ostatniego użycia valgrind jest trochę czasu, ale myślę, że to nie jest normalne zachowanie. Skowyt?

Rozwiązanie: Z tego, czego nauczyłem się z @Shawn, możliwe jest stłumienie błędów linkera za pomocą valgrind.supp plik. W moim programie uruchomiłem valgrind za pomocą--gen-suppressions=all opcja:

valgrind --gen-suppressions=all ./a.out 

Następnie wyodrębniam nowe kawałki ujęte w nawiasy i umieszczam je bezpośrednio w plikumy.supp:

{  
   <linker>
   Memcheck:Cond
   fun:index
   fun:expand_dynamic_string_token
   fun:_dl_map_object
   fun:map_doit
   fun:_dl_catch_error
   fun:do_preload
   fun:dl_main
   fun:_dl_sysdep_start
   fun:_dl_start
   obj:/usr/lib/ld-2.16.so
}  

Teraz mogę uruchomić valgrind za pomocą--suppressions opcja wskazania mojego nowego pliku, a wiadomości zostaną pominięte:

valgrind --suppressions=/home/foo/my.supp ./a.out
