简单来说,core dump说的是操作系统执行的一个动作,当某个进程因为一些原因意外终止(crash)的时候,操作系统会将这个进程当时的内存信息转储(dump)到磁盘上1。产生的文件就是core文件了,一般会以core.xxx形式命名。 如何产生Core Dump 发生doredump一般都是在进程收到某个信号的时候,Linux上现在大概有60多个信号,可以...
Core dumpsare an important part ofdebugging, as well as handlingirrecoverable system errorsand crashes. Once we ensure a core dump gets generated, we can turn to its analysis. In this tutorial,we explore how to indicate thelibrary pathswhen analyzing core dumps via theGNU Debugger (GDB). Firs...

https://github.com/dlmu2001/gdb_tutorial这里是一个实例程序 clone到本地后,执行编译命令, 直接在src目录下生成应用程序t1(linux环境下) g++ -g --std=c++11 main.cpp -lpthread -o t1 执行"gdb t1"可以直接启动程序进行调试,使用r执行程序,调试完使用q命令退出。
Lightweight GPU core dump support CUDA-GDB supports reading lightweight GPU core dump files. New environment variable: CUDA_ENABLE_LIGHTWEIGHT_COREDUMP can be used to enable this feature. 7.0 Release 13 CUDA-GDB, Release 12.2 GPU core dump support CUDA-GDB supports reading GPU and GPU+CPU ...

-core [file](-c) 讀入一個core dump檔案 -pid number (-p) 啟動attach模式,除錯一個執行中的行程。number是目標行程的pid -directory [directory] (-d) 將directory加入原始碼的搜尋路行 -readnow (-r) 一次讀取完所有的符號表,這會讓啟動gdb的時間變長,但在執行往後的除錯動作會較快速。
So now you know how to debug segmentation faults with gdb. This is extremely useful (I use it more often then I care to admit). The example also illustrated another very important point: ALWAYS CHECK THE RETURN VALUE OF MALLOC! Have a nice day. ...
