问题描述
我正在使用MinGW工具链构建Windows XP应用程序，它有时候会意外崩溃。所以，我试图使用调试器（Gdb），但程序退出与代码03之前，任何事情发生。事实上，我从GDB看到的是：
I'm building an application for Windows XP using the MinGW tool chain and it sometimes crashes unexpectedly. So, I'm trying to use a debugger (Gdb) but the program exits with code 03 before anything happens. In fact, all I see from GDB is:
使用代码03退出程序。
Program exited with code 03.
我怀疑有一些失败的动态链接的依赖（它们是Qt，VTK和ITK，所有建立与MinGW）。但是，这不会发生，当我只是正常运行程序。或者如果发生，它似乎是间歇性的，很好的程序启动和运行后。 注意：我也使用Cmake进行交叉编译。
My suspicion is that there is some failed dynamic linking of a dependency (which are Qt, VTK, and ITK, all built with MinGW). However, this does not happen when I just run the program normally. Or if it happens, it appears to be intermittent and well after the program is launched and running. NOTE: I'm also using Cmake for cross compiling.
我该怎么办？
推荐答案
通过信号（SIGABRT，< callback>）添加回调捕获调用以在关闭进程之前中止。如果在你点击 main（）之前发生这种情况，你可能需要诉诸一个静态的全局和编译器来捕捉它。
Add a callback via signal(SIGABRT, <callback>) to catch the call to abort before it shuts down the process. If this happens before you hit main() you might have to resort to a static global and compiler trickery to catch it.
