It rejects this source, which (AFAIU) is entirely kosher: #include void fn(int arr[]) { for (int j =3D 0; j < 5; ++j) printf("%d: %d\n", j, arr[j]); } int main() { fn((int[]) { 41, 42, 43, 44, 45 } ); return 0; } g++ -c t.cc t.cc: In function =E2=80=98int main()=E2=80=99: t.cc:11:37: error: taking address of temporary array fn((int[]) { 41, 42, 43, 44, 45 } ); ^ Still, I prefer to rewrite the case above, then to debug undiagnosed runtime problems from the original test case.
