我需要爲在Golang中編寫的服務器分析一些核心轉儲文件。但是我無法使用GDB展開堆棧信息（甚至是一些有用的信息）。GDB中的goroutine展開爲golang exe文件的核心轉儲
例如，我有一個main.go，它的代碼是：
package main
func main(){
panic("stupid")
}
而且我用的是以下獲得核心文件：
ulimit -c unlimited
GOTRACEBACK=crash ./main
然後我在運行gdb main core。而gdb，像下面這樣的東西。
[email protected]:/tmp/crash$ gdb main core

我發現這裏issue，但它並沒有給我一個解決方案，讓任何人都可以告訴我怎麼可以檢視堆棧跟蹤的夠程信息核心轉儲？感謝任何解決方案，謝謝！
