It can be resolved by having a base condition to return from the recursive function. A pointer must point to valid memory before accessing it.
What causes a segmentation fault in C?
Segmentation faults are a common class of error in programs written in languages like C that provide low-level memory access. They arise primarily due to errors in use of pointers for virtual memory addressing, particularly illegal access.
Is segmentation fault a runtime error?
The segmentation error is one of the runtime error, that is caused because of the memory access violation, like accessing invalid array index, pointing some restricted address etc.
What causes a segmentation fault?
Overview. A segmentation fault (aka segfault) is a common condition that causes programs to crash; they are often associated with a file named core . Segfaults are caused by a program trying to read or write an illegal memory location.

How do you debug a segmentation fault?
Debugging Segmentation Faults using GEF and GDB
- Step 1: Cause the segfault inside GDB. An example segfault-causing file can be found here.
- Step 2: Find the function call that caused the problem.
- Step 3: Inspect variables and values until you find a bad pointer or typo.

When to use core dump or segmentation fault?
A core dump is the recorded state of the working memory of a computer program at a specific time, generally when the program has terminated abnormally. Segmentation fault can also occur under following circumstances: a) A buggy program / command, which can be only fixed by applying patch.
When does a program report a segmentation violation?
When you run your program and the system reports a “segmentation violation,” it means your program has attempted to access an area of memory that it is not allowed to access. In other words, it attempted to stomp on memory ground that is beyond the limits that the operating system (e.g., Unix) has allocated for your program.
