+/// Use ARRAY_SIZE instead of dividing sizeof array with sizeof an element
+///
+//# This makes an effort to find cases where the argument to sizeof is wrong
+//# in memory allocation functions by checking the type of the allocated memory
+//# when it is a double pointer and ensuring the sizeof argument takes a pointer
+//# to the the memory being allocated. There are false positives in cases the
+//# sizeof argument is not used in constructing the return value. The result
+//# may need some reformatting.
