我需要为在Golang中编写的服务器分析一些核心转储文件。但是我无法使用GDB展开堆栈信息（甚至是一些有用的信息）。GDB中的goroutine展开为golang exe文件的核心转储
例如，我有一个main.go，它的代码是：
package main
func main(){
panic("stupid")
}
而且我用的是以下获得核心文件：
ulimit -c unlimited
GOTRACEBACK=crash ./main
然后我在运行gdb main core。而gdb，像下面这样的东西。
[email protected]:/tmp/crash$ gdb main core

我发现这里issue，但它并没有给我一个解决方案，让任何人都可以告诉我怎么可以检视堆栈跟踪的够程信息核心转储？感谢任何解决方案，谢谢！
