They arise primarily due to errors in use of pointers for virtual memory addressing, particularly illegal access. Segmentation Fault (core Dumped) C++ On systems using hardware memory segmentation to provide virtual memory, a segmentation fault occurs when the hardware detects an attempt to refer to a non-existent segment, or to refer to a Other optimizations could include translating the recursion into iteration, which given the structure of the example function would result in the program running forever, while probably not overflowing its stack. Dereferencing a null pointer will always result in a segmentation fault, but wild pointers and dangling pointers point to memory that may or may not exist, and may or may not

Linux Segmentation Fault Core Dump Location Incorrect use of the "&" (address of) and "*" (dereferencing) operators: Make sure you understand how these operators work.

Please use CODE tags. Finally, on some Unix and Linux systems, pointers that are initialized to null cannot be dereferenced; doing so will cause a segfault to occur.

Newer programming languages may employ mechanisms designed to avoid segmentation faults and improve memory safety. when I run my program (which is very small, [hangman]) i get: 'Segmentation fault (core dumped)'. The program has referred to a memory address outside of what was allocated to it, and the OS kernel responds by killing the program with SIGSEGV.
