问题 I recently found that a fairly large image manipulation program I'm writing in C on a Windows 8 machine has a bug when used in very particular circumstances. Unfortunately, the bug is causing my entire computer to come to a standstill so that my only option is to pull the plug on the computer (especially annoying when I'm working remotely...) Because it's an image manipulation program, I can't just flood it with print statements to isolate the problematic section - the problem occurs

问题 #include <iostream> #include <string> using namespace std; string crash() { } int noCrash() { } int main() { crash(); // crashes // noCrash(); // doesn't crash return 0; } The function crash(), crashes with Mingw g++ 4.6.2 and the function noCrash() executes with no issues. Why does the function returning string crash without a return statement? 回答1: Both are undefined behaviors, even noCrash can crash. 回答2: From standard 6.6.3/2 A return statement without an expression can be used only in

问题 What I've tried to print unicode is _setmode(_fileno(stdout), _O_U8TEXT); string str = u8"unicode 한글 hangul"; cout << str << endl; I used setmode to show and get unicode correctly, but It crashed with Debug Assertion Fail. However, _setmode(_fileno(stdout), _O_U16TEXT); wstring str = L"unicode 한글 hangul"; wcout << str << endl; _O_U16TEXT compile and print correctly. What should I do to use UTF-8? Do I have to find another trick? 回答1: _setmode mentions _O_U8TEXT and _O_U16TEXT (finally), but

问题 I am getting the crash shown below in Crashlytics. I am unable to understand where this is coming form within the app. Unfortunately I have never been able to generate this crash myself, but it is occurring in the wild. There is only one reference to the app name, and there is nothing that leads to show where in the app this is coming from. Is the fact that there is no data as to where in the app this occurs, an indication of an issue occurring during didFinishLaunchingWithOptionsand thus not

问题 I'm seeing a few crash reports that say Exception Type: EXC_CRASH (SIGABRT) Exception Codes: 0x0000000000000000, 0x0000000000000000 Exception Note: EXC_CORPSE_NOTIFY Termination Reason: TCC, This app has crashed because it attempted to access privacy-sensitive data without a usage description. The app's Info.plist must contain an NSPhotoLibraryAddUsageDescription key with a string value explaining to the user how the app uses this data. All very interesting, especially because my app never

问题 I have tried both the AVD on Android studio and Genymotion emulator. My ubuntu 16.04.1 crashes (freezes) when starting the android emulator. My computer has 16G memory. This happens after I installed the latest updates for my ubuntu in 19 Sept 2016. 回答1: I had same problem. Select in menu "Emulated performance" the "software", no automatical or hardvare 回答2: I had the same problem. You are probably using nouveau display driver instead of NVIDIA driver. You can check your driver with: lshw -c

问题 I changed some mysql config settings and set something wrong, now Docker container keeps restarting and I cannot find the my.cnf file to edit in host filesystem. I have tried aufs/diff folders but so far unable to find it. Also tried: find / -name my.cnf -exec nano {} \; But it does not bring up the file I changed. And I tried to change config.v2.json to start /bin/bash instead of mysqld and restarted docker, but yet it started mysqld (due supervisor or something?) using official mysql
