1. 您需要配置Cygwin以生成核心转储包含

1. You need to configure Cygwin to produce core dumps by including

error_start = x：\path\to\dumper.exe


在您的 CYGWIN 环境变量中（参见这里在转储部分了解更多信息）。

error_start=x:\path\to\dumper.exe

in your CYGWIN environment variable (see here in section "dumper" for more information). If you didn't do this, you will only get a stacktrace -- which may also help you in diagnosing the problem, though.

启动gdb如下所示：如果你没有这样做，你只会得到一个堆栈跟踪 - 这也可以帮助你诊断问题。将其附加到核心转储文件：

Start gdb as follows to attach it to a core dump file:

gdb myexecutable --core = mycorefile


现在，您可以使用常用的gdb命令打印一个stacktrace，检查变量的值，等等。

gdb myexecutable --core=mycorefile

You can now use the usual gdb commands to print a stacktrace, examine the values of variables, and so on.
