breakpoints

问题 I need to stop at breakpoint in case when other breakpoint was passed. Is it possible realize in VC++? 回答1: Why did you debug your two breakpoint using this way? If the debugging runs to the specific code line, it would call the conditional, and then trigger the conditional breakpoint, if it just runs to A code line, I don't think it could call the conditional in B code line unless it really calls/runs to this line. 来源： https://stackoverflow.com/questions/39342127/conditional-breakpoint

问题 I have written an if-clause that checks whether I should break the program for debugging or not: if (a < 0) { a = a; } a should not become negative, but I have found that it does, and I want to break for debugging to see why it becomes negative if that happens, hence I have written this if-clause. On the line a = a; I have set a breakpoint, which is supposed to stop the program if it enters the if-clause. The thing is that the line doesn't do anything (which is necessary in order not to mess

问题 I have a page where some JavaScript modifies a radio button to be not checked and another to be checked -- the HTML source contains the right checked attributes but when inspecting, the wrong one is checked. Also, when loading with JS off, the right one is checked. So I put a Chrome breakpoint on both for attribute modification and the breakpoints do not fire when reloading. I tried to set a breakpoint on a common parent div and it still doesn't fire. 回答1: Phil's comment is helpful but it

问题 I am trying to step through the simple bootloader shown in this tutorial: http://mikeos.berlios.de/write-your-own-os.html - so I can use the Qemu monitor to inspect the general registers for educational purposes. Eventhough I am able to connect Qemu and gdb and the breakpoint is set at the beginning of the bootloader (0x7c0), after hitting "c" on gdb the code just runs all the way till the end. I have read kvm may "confuse" gbd with virtual memory addresses, so I disabled it. This didn't work

问题 I set a breakpoint in my .java file. I started jetty via maven-jetty plugin. The java file where I set the breakpoint is also packaged into a JAR. Intellij stops at the breakpoint, but it shows me the file which is packaged into the JAR instead of the java file. It behaves as if I set a breakpoint in a java file of 3rd party libraries source code. How can I either make Intellij ignore my JAR or force Intellij to stop at my .java file? 回答1: The setup for this is two fold. Add the source to one

问题 I have used two different versions of GDB, both give problems in the following code: Trimmed down code in MyFile.h : template<class T> struct ABC: PQR<T> { void flow(PP pp) { const QX qx = XYZ<Z>::foo(pp); // Trying to set a breakpoint here, line no. 2533 ASSERTp(qx >= last_qx()); } } GDB 7.1: Reading symbols from /path_to_exec/exec...done. (gdb) break MyFile.h:2533 Note: breakpoint 1 also set at pc 0x121. Note: breakpoint 1 also set at pc 0x121. Note: breakpoint 1 also set at pc 0x121. Note:

问题 I originally used Visual Studio C++ Express, i've switched to ultimate and im currently confused as to why the debugger is moving my breakpoints, for example: if(x > y) { int z = x/y; < --- breakpoint set here } int h = x+y; < --- breakpoint is moved here during run time or random line of code < --- breakpoint set here random line of code return someValue; < --- breakpoint is moved here during run time It seems to do this at random locations in the code. Is there sometime i'm doing wrong here

问题 I'm trying to debug c/c++ code located in shared libraries which are loaded by ctypes.cdll.LoadLibrary() in python and then specific functions are called from python. The python code forks child processes, so I need to be able to break whether the c function is called from a python parent or child process. A dead-simple example: test.c // j = clib.call1(i) int call1(int i) { return i*2; } test.py import os, sys, ctypes path = os.path.abspath(os.path.join(os.path.dirname(sys.argv[0]), "test.so

问题 I need to stop on breakpoint after page reloading. I put a breakpoint in code but after reload it's being disabled. putting debugger; in code works fine. But I was wondering if there is a way to do it in firebug or chrome dev tools. 回答1: May be you have parameters in the url of the page that changes when your reload. http://website.com/page.html?stamp=20120516103456 You then load a new page each time you refresh. That may explain why your breakpoint disappear. 来源： https://stackoverflow.com

问题 Following the Android notepad tutorials using Eclipse 3.4.2 on OSX 10.5.6. I'm instructed to set a breakpoint in one of the following ways: Double click on the gray bar to the left of the editor pane. this just brings up the "Add Bookmark" window Select "Toggle breakpoint" in the context menu the only options in the context menu are "Go to Annotation..." (which is disabled), "Add Bookmark", "Add Task", "Quick Diff", "Show line numbers", "Folding" and "Preferences" My guess would be that the
