Dangling and pointers
* Dangling pointer bugs, which occur when a piece of memory is freed while there are still pointers to it, and one of those pointers is dereferenced.
Dangling pointers and wild pointers in computer programming are pointers that do not point to a valid object of the appropriate type.
Dangling pointers arise when an object is deleted or deallocated, without modifying the value of the pointer, so that the pointer still points to the memory location of the deallocated memory.

This extra limit, however, can be a rather large stumbling block for most C programmers, who are used to being able to manipulate their pointers directly with arithmetic.
A double-sided disk on the 1571 would have a capacity of 340 KB ( 70 tracks, 1, 360 disk blocks of 256 bytes each ); as 8 KB are reserved for system use ( directory and block availability information ) and, under CBM DOS, 2 bytes of each block serve as pointers to the next logical block, 254 x 1, 328 = 337, 312 B or about 329. 4 KB were available for user data.

However conceptually they are simple and work with early languages such as FORTRAN and BASIC which did not have pointers or objects.
If values are stored by reference, e. g. objects, null references can be used and so the cluster can be represented by a vector containing 3 slots for value pointers plus 4 slots for child references in the tree.

The mnemonics for pointers and arrays, which are not actual data types, are usually followed by the type of the data element itself:

pointers and through
Record access is done by navigating through the data structure using pointers combined with sequential accessing.
To find any particular record the programmer had to step through these pointers one at a time until the required record was returned.
A file's linkage section can contain pointers for which an attempt to load the pointer into a register or make an indirect reference through it causes a trap.
Smart pointers are opaque data structures that act like pointers but can only be accessed through particular methods.

; Low level multiprocessing: Instead of a single instruction pointer a Redcode simulator has a number of process queues, each containing a variable number of instruction pointers which the simulator cycles through.
The primary concern of the original engineers appears to have been fragmentation-that is, the repeated allocation and deallocation of memory through pointers leads to many small isolated areas of memory which cannot be used because they are too small, even though the total free memory may be sufficient to satisfy a particular request for memory.
If several pointers address ( are " aliases for ") a given hunk of storage, it may happen that the storage is freed or reallocated ( and thus moved ) through one alias and then referenced through another, which may lead to subtle ( and possibly intermittent ) lossage depending on the state and the allocation history of the malloc arena.
While pointers can be made invalid through a variety of mechanisms, ranging from carrying a null value to out-of-bounds arithmetic to illegal casts to producing them from random integers, a previously-valid reference only becomes invalid in two cases:

In a language with free pointers and / or non-checked array writes ( such as C ), the mixing of control flow data affecting the execution of code ( return addresses, saved frame pointers ) and simple program data ( parameters, return values ) in a call stack is a security risk, possibly exploitable through buffer overflows.
