debugging

问题 We have a .NET application using a lot of legacy components written in VB6. We were able to debug the VB6 code using native code debugger and generated pdb files in Visual Studio 2010. After upgrading to the VS 2012 (including Update 2) we cannot do this. The module window shows following message: Binary was not built with debug information. You can also find following message in the output window: Module was built without symbols. When I try to load symbols manually, I get following message:

问题 I'm compiling a program with -O3 for performance and -g for debug symbols (in case of crash I can use the core dump). One thing bothers me a lot, does the -g option results in a performance penalty? When I look on the output of the compilation with and without -g, I see that the output without -g is 80% smaller than the output of the compilation with -g. If the extra space goes for the debug symbols, I don't care about it (I guess) since this part is not used during runtime. But if for each

问题 I have 2 identical strings, they appear identical in the debugger (and Logger.log), but when I do string1 === string2 it returns false. How can I debug this? One of the string is a google drive file name, and one of the string is from a google sheet cell. I'm guessing there's an invisible character in one of the string but I have no way to see it. 回答1: Consider type of each variable typeof string1 === typeof string2 Consider length of each string string1.length === string2.length Loop through

问题 I ran valgrind to one of my open-source OpenCL codes (https://github.com/fangq/mmc), and it detected a lot of memory leaks in the OpenCL host code. Most of those pointed back to the line where I created the context object using clCreateContextFromType . I double checked all my OpenCL variables, command queues, kernels and programs, and made sure that they are all properly released, but still, when testing on sample programs, every call to the mmc_run_cl() function bumps up memory by 300MB

问题 Original Question (For reproduction instruction see Update II) I recently messed around with Visual Studio 2019 during a debugging session. I pinned some properties of the class "SqlCommand" as "Favorites". Since that moment I receive an error message "internal error retrieving local value" in the "locals". There is a "refresh" button on the right of the value column, and when I hit it, I get the message "Internal error in the expression evaluator." Now I am not able to unpin that specific

问题 I'm trying to debug an operating system that I am developing. When I start up the VM machine with VirtualBoxVM --startvm "X" --debug the VM starts paused, but when I execute the 'g' command to continue execution I get this error: g: error: The VM is already running But when I start my virtual machine without --debug , everything works fine, but I can't debug. Why does that error message appear? The VM starts stopped, so the message doesn't make sense and it doesn't allow me to debug my OS. 来源

问题 I'm using Rails 5 and Ruby 2.4. I want to start my server in debug mode so that I can debug in my IDE (Aptana Studio). I tried the below but get the error ... localhost:ruby-angular-app davea$ rails server --debugger Exiting /Users/davea/.rvm/gems/ruby-2.4.0/gems/rack-2.0.7/lib/rack/handler.rb:74:in `require': cannot load such file -- rack/handler/--debugger (LoadError) from /Users/davea/.rvm/gems/ruby-2.4.0/gems/rack-2.0.7/lib/rack/handler.rb:74:in `try_require' from /Users/davea/.rvm/gems

问题 I have setup Xdebug remote debugging with the following configuration: I placed a breakpoint in my phpunit test: <?php declare (strict_types = 1); namespace Tests\Api; class MyControllerTest extends ApiTestCase { public function myTest() { // Breakpoint goes here //Rest Of code } } Then I set the Xdebug to listen for the xdebug. ON the remote server (vagrant VM) I run the following commands: export XDEBUG_CONFIG="idekey=VSCODE" phpunit ./tests/app/MyControllerTest.php But my VSCode (ufing

问题 I'm just beginner in adonis framework in NodeJS but I have a good experience in laravel and lumen framework in laravel and lumen framework APIs I use dd() dump and die to debugging my app but in the AONIS framework, I don't know how to debug my API code . for IDE = I'm using Microsoft visual studio ( VS Code ) 回答1: Read this : https://code.visualstudio.com/docs/nodejs/nodejs-debugging (from @damitj07) In summary : You need to create new lauch.json like: { // Use IntelliSense to learn about
