I seem to be getting the same errors as @wwlwwl and @Immaterial using c++. I can pass the sample tests fine but on "Attempt", I fail with :

Time: 1936ms
Test Results:
 sumOfDivided_Tests

with a red border and a green arrow next to "SumOfDivided_Tests." If I change my code to return output + "Thing"; Then the output on "Attempt" becomes:

Time: 1743ms Passed: 0 Failed: 2
Test Results:

Which is apparently the correct output with "Thing" appended. Others have suggested that these issues are usually caused by segfaults but I am not sure that that is the case here. Clearly it is possible to pass this kata in c++ but I am not sure why I am failing.
