Originally reported on Google Code with ID 471

The following should detect an error, but is not.

    int * p = new int[10];
    delete p;

Must use delete [] when allocated with new [].  This is seen with gperftools-2.0

The heap checker will find these memory leaks for you. Not sure how we would do detection
of this condition without adding additional meta data to the memory allocation itself
which would negatively impact performance. Pretty sure Valgrind will detect these but
have you noticed how slow it runs :)
