Correct delete[] use

Thanks for your work, it's greatly appreciated!

One thing though: I think it might be better to replace these with appropriate STL smart pointers instead of explicit delete[] operators. That way, the probability of introducing similar memory leaks in the future would be reduced (like for example when someone decides to use another return statement somewhere earlier in the function without realizing there is cleanup to do), and it would also make the code exception safe.

Jenkins, test this.

I also prefer to use shared pointers; however I merge this PR because fixing bugs is top priority.
