debugging

问题 I have programmed a boost::thread application, where I might have some race conditions. I want to debug this program. Therefore I used the following valgrind tools: halgrind drd unfortunately they have a very false positive rate. So with the really simple program below valgrind --tool=drd complains about 94 errors, where no should be. So with my complex program I get about 15000 errors. So it is really hard to find the actual error. I could reproduce this behavior with the following boost

I found this post from a year ago, and I'm using R version 2.11.1 (2010-05-31) , but still getting error messages without line numbers. Any solution? 回答1: The answers given there are still valid. Returning line numbers from a script ain't that straight-forward, but R can give you a lot more information on where the error can be found. You could use the error options to save the info in a

问题 I have used Postsharp a few years ago to trace program flow during execution without needing to manually add trace statements to the methods. Is there any other new ways to trace execution to to debug output in a similar way? (Preferably a way that doesn't need to instrument the built assemblies. Maybe not possible?) 回答1: If you only want this ability at debug time, there's Microsoft IntelliTrace that's a part of Visual Studio 2010 Ultimate, and there's Sergey Vlasov's RunTime Flow. The

问题 Is there any short-key to terminate all active debug launches, remove all terminated launches from debug view and to show debug history quick menu? I found short key to terminate single launch from here What is the short cut in eclipse to terminate debugging/running? 来源： https://stackoverflow.com/questions/14831744/short-cut-key-for-java-debugging

问题 I am new to driver stuff. I have tried to debug the kernel driver using serial COM port without success. Could someone show me proper direction how to fix the problem? I am seeing the following messages on kd console. ERROR: DavReadRegistryValues/RegQueryValueExW(4). WStatus = 127 ERROR: DavReadRegistryValues/RegQueryValueExW(5).

问题 I've got a .NET CF (C#) mobile application that I run on a windows emulator. This application uses a sqlce database, and also is controlled by a number of config-like files. I frequently need to change back and forth between different debugging environments - i.e. I need different versions of the database as well as the config files - b/c the application is being used differently in each of the environments. My initial thought was to use different emulators for different environments, but

问题 I'm trying to debug a Next.js app with a custom server which I normally run with a dev Yarn script that executes node server.js . VSCode includes a Node.js debugging extension and this guide, which I've followed. I created a new Yarn script called dev:debug that runs node --inspect server.js , and the following configuration in launch.json: { "type": "node", "request": "launch", "name": "Debug via Yarn", "runtimeExecutable": "yarn", "runtimeArgs": ["dev:debug"], "port": 9229 } However some
