Hi! This is actually the same crap as I had to work around in test-string.h, ie. x86_64 aligns preinit_array etc. to 16 bytes because they are >= 16 bytes, yet its actual size is 24 bytes. /* x86-64 ABI requires arrays greater than 16 bytes to be aligned to 16byte boundary. */ Linker script of course doesn't expect .init_array/.fini_array/.preinit_array sections to be more than word aligned and thus the labels around them are on wrong positions. 2002-12-10 Jakub Jelinek <jakub@redhat.com> * elf/tst-array1.c (preinit_array, init_array, fini_array): Explicitely align the array to sizeof (void *). * elf/tst-array2dep.c (init_array, fini_array): Likewise. --- libc/elf/tst-array1.c.jj 2002-11-07 23:28:04.000000000 +0100 +++ libc/elf/tst-array1.c 2002-12-10 16:01:54.000000000 +0100 @@ -35,7 +35,7 @@ preinit_2 (void) } void (*const preinit_array []) (void) - __attribute__ ((section (".preinit_array"))) = + __attribute__ ((section (".preinit_array"), aligned (sizeof (void *)))) = { &preinit_0, &preinit_1, @@ -60,7 +60,8 @@ init_2 (void) write (STDOUT_FILENO, "init array 2\n", 13); } -void (*const init_array []) (void) __attribute__ ((section (".init_array"))) = +void (*const init_array []) (void) + __attribute__ ((section (".init_array"), aligned (sizeof (void *)))) = { &init_0, &init_1, @@ -85,7 +86,8 @@ fini_2 (void) write (STDOUT_FILENO, "fini array 2\n", 13); } -void (*const fini_array []) (void) __attribute__ ((section (".fini_array"))) = +void (*const fini_array []) (void) + __attribute__ ((section (".fini_array"), aligned (sizeof (void *)))) = { &fini_0, &fini_1, --- libc/elf/tst-array2dep.c.jj 2002-11-07 23:28:04.000000000 +0100 +++ libc/elf/tst-array2dep.c 2002-12-10 16:02:34.000000000 +0100 @@ -34,7 +34,8 @@ init_2 (void) write (STDOUT_FILENO, "DSO init array 2\n", 17); } -void (*const init_array []) (void) __attribute__ ((section (".init_array"))) = +void (*const init_array []) (void) + __attribute__ ((section (".init_array"), aligned (sizeof (void *)))) = { &init_0, &init_1, @@ -59,7 +60,8 @@ fini_2 (void) write (STDOUT_FILENO, "DSO fini array 2\n", 17); } -void (*const fini_array []) (void) __attribute__ ((section (".fini_array"))) = +void (*const fini_array []) (void) + __attribute__ ((section (".fini_array"), aligned (sizeof (void *)))) = { &fini_0, &fini_1, Jakub
