Heapchecker does not detect mismatched delete #471

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago 
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 :)
