--- Comment #1 from Martin Liška <marxin at gcc dot gnu.org> ---
And a similar problem from openssl:
$ cat bn_ctx.i
int BN_CTX_startBN_STACK_push_newsize;
void
memcpy2(void *__dest, void *__src, int __len) {
long __trans_tmp_1 = __builtin_dynamic_object_size(__dest, 0);
__builtin___memcpy_chk(__dest, __src, __len, __trans_tmp_1);
}
int *CRYPTO_malloc() __attribute__((alloc_size(1)));
void
BN_CTX_startBN_STACK_push_st() {
int *newitems = CRYPTO_malloc(BN_CTX_startBN_STACK_push_newsize);
memcpy2(newitems, BN_CTX_startBN_STACK_push_st, sizeof(int));
}
$ gcc bn_ctx.i -c -m32 -O3 -D_FORTIFY_SOURCE=3
bn_ctx.i: In function ‘BN_CTX_startBN_STACK_push_st’:
