Qt creator 2.5 : GDB意外退出，我怎么知道GDB崩溃的原因？

Question

我下载了QT Creator 2.5，使用我从Qt站点下载的mingw : MinGW-gcc440_1设置QT Creator 2.5和windows全局路径中的路径。当我编译时我处于调试模式，但是当我尝试使用GDB im进行调试时，在错误消息窗口中得到这个错误:标题中意外的GDB退出，gdb进程崩溃。我使用的是windows 7，64位，但g++是32位编译的，我试图在QT Creator 2.5中搜索一些日志，但没有成功。

编译行示例：

g++ -c -g -frtti -fexceptions -mthreads -Wall -DUNICODE -DQT_LARGEFILE_SUPPORT -DQT_DLL -DQT_GUI_LIB -DQT_NETWORK_LIB -DQT_CORE_LIB -DQT_HAVE_MMX -DQT_HAVE_3DNOW -DQT_HAVE_SSE -DQT_HAVE_MMXEXT -DQT_HAVE_SSE2 -DQT_THREAD_SUPPORT -DQT_NEEDS_QMAIN -I"c:\Qt\4.8.2_mingw\include\QtCore" -I"c:\Qt\4.8.2_mingw\include\QtNetwork" -I"c:\Qt\4.8.2_mingw\include\QtGui" -I"c:\Qt\4.8.2_mingw\include" -I"." -I"lib_json\include" -I"lib_json\include\json" -I"c:\Qt\4.8.2_mingw\include\ActiveQt" -I"debug" -I"." -I"c:\Qt\4.8.2_mingw\mkspecs\win32-g++" -o debug\main.o main.cpp

好的，我有调试器的日志，但我很难找到问题：

该gdb是6.8版。IIRC Creator推荐7.0，那么你有没有尝试过升级GDB？

你从哪里得到这个GDB的？在一些mingw发行版中提供的版本在Qt Creator中使用时会中断。您可以从这里获取Qt创建者团队认为可以工作的http://builds.qt-project.org/
