gdb 在 macOS 上不读取核心转储

Question

我已经在 OSX 10.10.5 上安装了 Homebrew 的 gdb 公式，以便向 weechat 开发人员发送回溯(因为每次我这样做时，随 Homebrew 安装的 weechat 都会崩溃/退出)。

在尝试读取核心文件时遇到此问题:

gdb /usr/local/bin/weechat /cores/core.70087
GNU gdb (GDB) 7.10

Reading symbols from /usr/local/bin/weechat...(no debugging symbols found)...done.
"/cores/core.70087": no core file handler recognizes format
(gdb)

我尝试使用 lldb 而不是 gdb 来执行此操作:

$ lldb /usr/local/bin/weechat /cores/core.70087
(lldb) target create "/usr/local/bin/weechat"
Current executable set to '/usr/local/bin/weechat' (x86_64).
(lldb) settings set -- target.run-args  "/cores/core.70087"
(lldb) bt full
error: bt [<digit>|all]
(lldb) bt all
error: invalid process
(lldb) bt
error: invalid process
(lldb) thread backtrace
error: invalid process
(lldb)

不知道我在做什么，只是尽我所能来解决这些崩溃问题。

您应该能够启动 lldb 作为

$ lldb --core "/cores/core.70087"
