clang-22 with enable-asan and enable-ubsan enabled fails with error
crypto/sparse_array.c:93:21: runtime error: call to function alg_copy
through pointer to incorrect function type 'void (*)(unsigned long, void *, void *)'
ossl_sa_##type##_doall(const SPARSE_ARRAY_OF(type) * sa,
void (*leaf)(ossl_uintmax_t, type *))
{
ossl_sa_doall((OPENSSL_SA *)sa,
(void (*)(ossl_uintmax_t, void *))leaf);
}
typed doall(_arg) expect leaf to have type, but generic code is using
void *, and the type-casting cases the error.
