<pre>int a[1];

int main() { ++a[c]; }
clang-3.8.0-2.fc24.x86_64
/tmp/1j.C:3:17: error: no viable overloaded operator[] for type 'int [1]'
int main() { ++a[c]; }
~^~
gcc-6.1.1-3.fc24.x86_64
/tmp/1j.C: In function ‘int main()’:
/tmp/1j.C:3:17: error: no match for ‘operator[]’ (operand types are ‘int [1]’
and ‘C’)
int main() { ++a[c]; }
^
It was unclear for me why the error is reported by clang (sure in a more
complicated real world case). I had to use GCC to make it clear to me.</pre>
