breakpoints

Thread 1: Stopped at breakpoint 1

问题 I have a problem with XCode 4.3.2, and I cannot figure out what it is. I have set a breakpoint, but instead that XCode stops at the line the breakpoint is set, it shows me the thread log. I am going crazy here. So, this is the page I see in XCode when it comes to my breakpoint. It does this is several projects and tried it both with and without zombie enabled. 回答1: I searched google for resetting XCode, and it seems that this post helped me out: http://www.developers-life.com

Eclipse pausing without a breakpoint

自作多情 提交于 2019-11-29 14:19:17
While debugging my project in Eclipse, it will (repeatably, at the same point in the code) pause execution as if it's reached a breakpoint. No exceptions are thrown, the project has no breakpoints, and if I hit resume, it carries on without a problem. What could be causing this behaviour? The Eclipse debugger pauses if the code throws an exception - at least it does for me (maybe this can be toggled). Just un-pause the thread and you'll most likely see a stacktrace being printed to STDERR. Your code and the binaries that you are debugging are not in sync. Try creating a break point and then

Why does Visual Studio 2008 skip over my break points?

流过昼夜 提交于 2019-11-29 14:15:23
I am running Visual Studio 2008 with SP1. When I debug an application, it will skip over my break points. For example, I have two lines of code, each call a method. I will put a break point on both lines. I will run it one time, and it ill stop at the first break point, but not the next one. I will run it again, and it ill hit the second one, not the first one. I have tried to clean the solution and a rebuild. I do have multiple projects in the solution. Symbol file incompatibility It's possible that your symbol file (.pdb) is out of sync with your source code. A common symptom of this is:

How to break on instruction with a specific opcode in GDB?

跟風遠走 提交于 2019-11-29 14:06:15
I have the assembly code of some code that will be executed at a point in the program. I don't know the address of the code in memory. Is it possible to make gdb break when the current instruction matches with an inputted instruction? For example I want gdb to break whenever gdb reaches this instruction: leaq 0x000008eb(%rip),%rax No, this is not possible and it would also be very inefficient to implement. Debugger's typically support two kinds of breakpoints: Hardware Breakpoints : The debugger asks the CPU to raise a special exception interrupt when some event occurs, like some location in

Using GDB without debugging symbols on x86?

痴心易碎 提交于 2019-11-29 11:38:38
问题 How do I use GDB to debug a program which do not have debugging symbols on a 32-bit x86 processor? Inspecting the function arguments, local variables, resolving pointers would be useful to know how to do. The intention is not really to use this for reverse engineering, as I'm sometimes just too lazy to install the debugging symbols and would be great to know how to get some basic information out of gdb. 回答1: To start out, you can do; gdb "whatever" break __libc_start_main r that will setup a

Visual Studio does not allow breakpoints in MVC views

Sometimes Visual Studio does not allow me to set breakpoints in MVC views. This has happened to me scores of times, but it doesn't happen for every view and I don't know why. When you click on the left-hand bar to place a breakpoint, it places a white circle instead of the normal red circle. The message when you hover over it is "The breakpoint will not currently be hit. The source code is different from the original version." It goes on to describe how to allow breakpoints to be hit, but that produces strange results and I don't want that anyways. If the error is correct, then I want to run

Debug Break on Win32 Api functions

泪湿孤枕 提交于 2019-11-29 09:08:41
问题 I would like to have a break on the SetTimer function in order to see which components register what timers with what values. Is this possible? 回答1: Yes, you can do this. First make sure you have public symbols setup for your debugger. SetTimer lives in user32 but that is just what it is exported as. The easiest way to do this is with the command line debugger, NTSD. We need its real name, so look for symbols in user32 that match: 0:000> x user32!*timer* 759992b9 USER32

PyDev Breakpoints in App Engine 1.7.6 broken?

扶醉桌前 提交于 2019-11-29 06:56:26
问题 I just upgraded to the App Engine 1.7.6 SDK for my python app and realised that breakpoints no longer work in PyDev (Eclipse plugin) when using the new dev_appserver.py . Does anyone know of a way of enabling them again? I assume the new server is spawning a new process for the web server, and the debugger isn't attaching to that one. I'm not sure how to configure it to do that though. In the meantime I am using the old_dev_appserver.py server. 回答1: UPDATE 2012-07-27: Following the comment, I

Xcode: EXC_BREAKPOINT (EXC_ARM_BREAKPOINT, subcode=0xe7ffdefe)

I'm getting an EXC_BREAKPOINT (EXC_ARM_BREAKPOINT, subcode=0xe7ffdefe) error while running my app on a iOS7 device. The thing is, it runs smoothly on iOS7 simulator. By using breakpoints, I've found the error occurs in line 6. required init(coder aDecoder: NSCoder) { personPicker = ABPeoplePickerNavigationController() super.init(coder: aDecoder) personPicker.peoplePickerDelegate = self } /*error line*/ @IBAction func BPressed(sender: AnyObject) { self.presentViewController(personPicker, animated: true, completion: nil) } This error is new, and didn't appeared on my device until I've added

Debugging and counting breakpoint hits

痞子三分冷 提交于 2019-11-29 05:33:49
Sometimes when I examine a code I didn’t write, I launch eclipse in debug mode and use figures to understand a program. For example, if they are n items retrieved from the DB, it can be interesting to know that there’re n processed items in a service, etc. When loops are used, things get more complicated: if we’re in a “while” loop, the number of execution is not defined and if there are alternatives, the flow of execution can greatly change. For this purpose, I sometimes set a breakpoint in a portion of code and count how many times we reach it. Of course, it’s not very convenient and I
