crash

问题 Help! I have a Java headless iterative calculation-intensive servlet running 24/7 on Unix, that a few builds ago has started crashing after about a day or so, and I can't for the LIFE of me get a crash log / dump / indicator of any kind as to why. No manner of JVM arguments, shut down hooks, etc have helped me to get any sort of log as to what might be happening. Crash is not reproducible on-command, or predictable. Happens roughly every 20-30 hours. OS: Amazon Linux AMI Hardware: AWS EC2 T3

问题 I have the following simple code in NSAppDelegate func applicationDidFinishLaunching(aNotification: NSNotification) { var opt:Int? NSLog("\(opt)") NSLog("\(opt!)") NSLog("done") } Now when I run that in debug mode it tells me what we all know about unwrapping nil optional. But when I run that for release it silently exits the app with no message at all. No console log. No dump. Nothing! What's going on here? 回答1: Apple has asked me to check if the bug has been fixed with Xcode 6.3 beta 3 with

问题 I need help figuring this crash out. I checked stackoverflow for answers, but non of the answers relates to my situation. This is my code. - (void)addImagesActionSheetClickedButtonAtIndex:(NSInteger)buttonIndex { // Cancel if (buttonIndex == 2) return; //Take picture if (buttonIndex == 0) { //Take picture isFromLibrary = NO; [self.imagePicker setSourceType:UIImagePickerControllerSourceTypeCamera]; [self.navigationController presentViewController:self.imagePicker animated:YES completion:NULL];

问题 I have a UIControl subclass in my iOS App (I'm using iOS 4.3), and part of the subclass is a method called "setButtonColor:(UIColor)bc". Whenever I call this method from my code, it works fine...but only if I use a built-in color like greenColor or redColor. If I use " colorWithRed:green:blue:alpha ," to make my own color it crashes with this message in the console: -[UIDeviceRGBColor set]: message sent to deallocated instance 0x4e61560 Here's the setButtonColor: method: -(void)setButtonColor

问题 I am writting a program which uses boost python embedded. My program works no problem on Linux Mint but on Windows its a huge pain. I am using MingW so I tried creating an import lib following instructions from another question on this site. With all that in mind the program compiled and linked, python34 dynamically and boost python statically. My program crashes though and I cant tell for the life of me why, I followed the execution and it stops at: "import(" main ");" // My python

问题 I simply try to delete a row from a UITableView with the following code: - (void)tableView:(UITableView *)tableView commitEditingStyle:(UITableViewCellEditingStyle)editingStyle forRowAtIndexPath:(NSIndexPath *)indexPath { if (editingStyle == UITableViewCellEditingStyleDelete) { [self.tableView deleteRowsAtIndexPaths:[NSArray arrayWithObject:indexPath] withRowAnimation:UITableViewRowAnimationFade]; } } The problem is that my app crashes. (GDB: Program received signal: "EXC_BAD_INSTRUCTION".)

问题 I have two programs, both running on an Android 2.3.4 platform - one is a C++ binary in a daemon form, compiled with cmake, the other is a apk with jni part compiled with ndk-build. I'm using android-ndk-r6. I'm using protobuf messages and local unix sockets to pass data between them. I'm using the SerializeAsString and ParseFromString methods. Here is a snippet AbstractMessage protobuff_msg; protobuff_msg.set_id ( 1 ); //TODO: for now hardcoded, later can be used for request-response pairs

问题 So I've been using MinGW GCC version 4.4 or a while, and decided it's time to upgrade. I went to the MinGW website and downloaded the latest version of GCC (4.7.0). After deleting my previous version, and installing the newest version, even the simplest program will crash. For example, if I compile this program #include <iostream> using namespace std; int main () { cout << "Hello, World" << endl; return 0; } with the command line g++ hello.cpp -o hello.exe It will print out "Hello, World" and
