implementing Struct Initialization and Function Return in C - Unexpected Segmentation Fault
I'm converting an old project and This might be a silly question, but I'm relatively new to this, so bear with me... I've been struggling with this for a few days now and could really use some help... I'm working with a segmentation fault when trying to return a struct from a function after initializing it on the stack. My code aims to create a simple data structure that holds a string and an integer, but when I attempt to access the struct's members after the function call, it leads to unpredictable behavior. Here's the relevant code snippet: ```c #include <stdio.h> #include <string.h> typedef struct { char name[50]; int age; } Person; Person createPerson(const char* name, int age) { Person p; strncpy(p.name, name, sizeof(p.name)); p.age = age; return p; // Returning struct from function } int main() { Person p = createPerson("Alice", 30); printf("Name: %s, Age: %d\n", p.name, p.age); return 0; } ``` I expected the program to print "Name: Alice, Age: 30", but instead, it crashes with a segmentation fault when I access the `p` struct's members in `main()`. I also tried changing the return type to a pointer and allocating memory dynamically using `malloc`, but that led to a memory leak since I didn't free the memory afterwards. Additionally, I verified that the `createPerson` function is called correctly, and the logic of copying the string seems fine too. I'm using GCC version 10.2 on Ubuntu 20.04. Can anyone help identify why this segmentation fault occurs and suggest the best practice for returning structs from functions in C? This is part of a larger service I'm building. Am I missing something obvious? Any advice would be much appreciated. For context: I'm using C on Debian. Has anyone dealt with something similar?
