I'm a beginner recently working on CSAPP attack lab on Ubuntu22.04. I download the files and run ctarget in terminal, ./ctarget Typically, CTARGET is expected to receive stdin as code injection , and injecting too much characters leads to segmentation…
The following C program creates an empty file of a specified length. I have tested this on my local Ubuntu 20.04 laptop and it works. I am now running it in an instance at Digital Ocean (Ubuntu 22.04), but the…
Using ubuntu, python and gstreamer to grab an rtsp stream I get segmentation fault, resulting into not being able to view the rtsp stream. Using the python application results in segmentation fault with rtspsrc, but running a rtspsrc from terminal…
Wait, come back, I promise this isn't about uninitialized pointers! The problem I have written some unit tests using Criterion. The code under test doesn't matter; the problem crops up in the test itself. Here's a simplified version of the…
Here i am trying to solve the infamous eight queens problem, and when i finally thought i got it,a segmentation fault hits me out of nowhere, the code i wrote is: #include<unistd.h> #include<stdio.h> int isLastBoard(int *chessBoard){ for(int i = 0…
I wrote a simple http server in C and I was now trying to send html responses. I wrote a function to read the html file and put it in a string but turns out it's only working on small…
The following issue seems to touch R, conda installation issues and possibly memory mapping. Here is a minimal example that already results in the problem: Running mamba create -n R_test r-base -c r seems to work just fine. But when…
I am beginning with Rust and I design a plugin mechanism based on libloading as learning opportunity, beside the Rust book. I am unsure if the issue I have is due to misunderstanding with Rust or libloading, or if there…
I am stuck on the following problem. Consider this code: #include <stdio.h> #include <stdint.h> #include <stdlib.h> void runme() { printf("Hello, world!n"); exit(0); } int main(char argc, char **argv) { if (argc != 2) return 1; void (*buffer[8])(void); buffer[(int8_t) argv[1][0]] =…
I am trying to understand why the behaviour of segfault messages can differ depending on execution environment. I have the following C code that I am using to deliberately trigger a segfault: #include <stdio.h> int main() { int* p =…
