更新了静态库，现在应用程序在堆栈上的任何内容之前退出。如何调试
我正在 OS X 上开发一个 unix 控制台应用程序。我刚刚更新了三个静态链接库（hdf5 及其依赖项 szip 和 z）。全部重建后，应用程序在启动后立即退出代码 1。我不知道如何在 gdb 中进一步探索这个问题，因为应用程序退出时堆栈上没有任何内容。我确实使用 otool -hv 确认所有库都是为 X86_64 架构构建的。
我可以并且已经通过恢复到以前的库二进制文件来让我的应用程序再次工作，但我想更多地了解应用程序运行的最早阶段发生了什么导致它退出。
GDB 结果如下：
gdb ./build-deb/xapp/xapp

I am developing a unix console application on OS X. I just updated three statically linked libraries (hdf5 and its dependents szip and z). After a rebuild all, the application exits code 1 immediately after launch. I'm unaware of how to explore the problem further in gdb because nothing is on the stack by the time the app exits. I did confirm using otool -hv that all libraries are built for X86_64 architecture.
I can, and have, gotten my app working again by reverting to the previous library binaries, but I'd like to know more about what is going on during the earliest stage of the application run that is causing it to exit.

它看起来像一些名为 exit(1) 或 return 1 的代码，因此我首先在 main 的开头放置一个断点，然后单步执行，直到调用退出处理程序，或在退出处理程序中中断。
It looks like some code called exit(1) or return 1 so I would start by putting a breakpoint at the start of main and stepping until the exit handler gets called, or break in the exit handler.
