Windows系统MSVC编译器的dump文件
debug模式
生成exe自带生成pdb文件，所以无需处理。
1.生成dump文件
通过修改注册表，增加注册表HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\Windows Error Reporting\LocalDumps
具体见：利用vs 分析DMP文件、pdb文件定位release下的异常崩溃_小飞侠hello的博客-CSDN博客_dmp文件 用vs 查看
2.使用Windbg调试dump
a.配置Symbol file path（符号路径）、Source file path（源文件路径）、 Image File Path（可执行文件路径）。
b.执行命令 !analyze -v
符号路径：把生成的pdb文件所在目录及微软符号服务器加进去
源文件路径：源代码文件夹
可执行文件路径：可执行文件路径（这个选择具体的exe文件报错，只能选exe文件所在文件夹）
具体见：利用windbg分析程序崩溃生成的dmp文件_小飞侠hello的博客-CSDN博客_windbg分析dmp文件
Release模式
1.生成.pdb文件
release版本是不会自动生成pdb文件的。需要手动设置。
办法是：在pro文件中加入
QMAKE_CXXFLAGS_RELEASE = $$QMAKE_CFLAGS_RELEASE_WITH_DEBUGINFO
QMAKE_LFLAGS_RELEASE = $$QMAKE_LFLAGS_RELEASE_WITH_DEBUGINFO2.其他步骤和debug一样
举例
MainWindow::MainWindow(QWidget *parent)
: QMainWindow(parent)
{
int *pa = new int[2];
int *p = nullptr;
*p = 1;

Linux系统core文件
QT程序在崩溃时生成内存镜像文件，windows下生成的叫dump文件，linux下生成的叫core文件.
生成core文件
1.在pro 配置添加
QMAKE_CC += -g
QMAKE_CXX += -g
QMAKE_LINK += -g其他的步骤和一般的linux程序一样。都是 设置ulimit -c unlimited 、更改core文件、运行可执行程序生成core文件。参考：https://blog.csdn.net/baidu_16370559/article/details/128499174?csdn_share_tail=%7B"type"%3A"blog"%2C"rType"%3A"article"%2C"rId"%3A"128499174"%2C"source"%3A"baidu_16370559"%7D
2.调试core文件
第一种办法：和一般linux程序一样，通过gdb调试。
调用 gdb 程序名 core文件名
参考：https://blog.csdn.net/baidu_16370559/article/details/128499174?csdn_share_tail=%7B"type"%3A"blog"%2C"rType"%3A"article"%2C"rId"%3A"128499174"%2C"source"%3A"baidu_16370559"%7D
第二种办法：使用qt creator
1、Debug->Start Debugging->Load Core File
2、在弹出的窗口选择对应的文件
3、点击OK，开始调试，会看到code里的信息
