segmentation-fault

问题 I was learning OpenGL using GLFW, and didn't have a great understanding of makefiles at the time. I had OpenGL working, but I decided to learn makefiles more. I came up with this after a lot of websites, hours, and trial and error: EXENAME = "OpenGL Demo" CC = gcc SRCS = ../src/OpenGLDemo.c OBJS = $(SRCS: .c = .o) CFLAGS = -Wall -g -c LIBS = -L./libs -lglfw3 C:/Windows/SysWOW64/opengl32.dll C:/Windows/SysWOW64/glu32.dll all: opengldemo exe exe: $(OBJS) $(CC) $(OBJS) -o $(EXENAME) $(LIBS)

问题 In this code, for vector size, n >=32767, it gives segmentation fault, but upto 32766, it runs fine. What could be the error? This is full code. #include<cstdio> #include<cstring> #include<cmath> #include<queue> #include<utility> #include<algorithm> #include<sys/time.h> using namespace std; #define MAX 100000 bool compare(pair<int,int> p1,pair<int,int> p2) { if(p1.second < p2.second) return 1; else if(p1.second > p2.second) return 0; if(p1.first <= p2.first) return 1; else return 0; } int

问题 Closed. This question needs debugging details. It is not currently accepting answers. Want to improve this question? Update the question so it's on-topic for Stack Overflow. Closed 2 days ago . Improve this question I am new in PyQt in python and I have been working on a GUI lately. One of the parts of the GUI is a button which is supposed to get rid of all lines currently in the GUI. Because I am using threads, the way I implemented this feature is to have a GUI attribute, self.clear, which

问题 I'm quite new to x86 assembly, and I'm trying to build off a hello world program. I'm trying to make a subroutine, that writes a single byte to stdout, but i've hit a problem. The line mov ebx, [esp+1] (to load the byte passed, when I call the subroutine) causes a segfault. I've tried xoring the ebx register with itself, to make sure that it is empty, to make sure, that it doesn't mess with the syscall _start: push 32h call _writeByte ; This just jumps to an exit routine jmp _exit _writeByte:

问题 In the way to understanding binaries (Virtual memory layout, execution...etc), I've written a C code that declares a global string which contains bytes of an executable code, then i overwrote the return address from the main() function to that executable code using a simple trick by declaring a pointer ( PTR ) in main() which is a local area of memory reserved on the stack 2 WORDS far away from the return address from the main() , so all i do is assigning the address of the return address to

问题 I have an f2py module that I am using. The core of the code I did not write myself, just the f2py wrapper to use it. Because of time constraints, and the knowledge that his code is short term need only, meaning I want to throw it away, not fix it, what I want to do is just catch the behavior when a segfault occurs and try again. The below code is an example: sums.f90 subroutine bad(a, b, c) real, intent(in) :: a, b real, intent(out) :: c real, allocatable :: d(:) real :: r call random_number

问题 I'm struggling a bit with reading files and writing into files. I've been working on this problem for a few days and I just can't seem to get it. The program is supposed to recover some jpeg files from a memory card. With the following code I keep getting a segmentation fault. Can you guys see where I went wrong? Here is my code below: Hope you guys can help! #include <stdio.h> #include <stdlib.h> #include <cs50.h> int main(int argc, char *argv[]) { //Ensure only one command line argument//
