Question

使用原始的gdb (Debian 8.2.1-2)在我的Linux / x86-64 / Debian Sid AMD2970WX桌面上调试RefPerSys（GPLv3 +，在gitlab上）提交ec4ab756d302056cace0b时，我得到了重现

rimski.x86_64 ~/refpersys 14:39 .0 % gdb --args ./refpersys --object-tinybenchmark1

warning: File "/home/basile/refpersys/.gdbinit" auto-loading has been declined by your `auto-load safe-path' set to "$debugdir:$datadir/auto-load".
To enable execution of this file add
    add-auto-load-safe-path /home/basile/refpersys/.gdbinit
line to your configuration file "/home/basile/.gdbinit".
To completely disable this security protection add
    set auto-load safe-path /

For more information about this security protection see the
"Auto-loading safe path" section in the GDB manual.  E.g., run from the shell:
    info "(gdb)Auto-loading safe path"

通过这样的gdb调用而不进行诊断来消化我的./.gdbinit的神奇之处是什么？ .gdbinit包含：

# file refpersys/.gdbinit 
# GPLv3+ licensed 
add-auto-load-safe-path ./.gdbinit 
break abort 
break rps_fatal_stop_at 
set max-value-size 67108864

我可以（过去做过）从其源代码重建gdb。但是今天，我很me脚，更喜欢专注于我的错误。

FWIW

正如启动gdb时的警告所言：

To enable execution of this file add
    add-auto-load-safe-path /home/basile/refpersys/.gdbinit
line to your configuration file "/home/basile/.gdbinit".

您似乎误解了，并将该行添加到了仓库中的.gdbinit文件中，但是它需要进入您的主目录。

如果.gdbinit文件在您的主目录中尚不存在，则可以创建该文件，并且仅在上面添加所需的行即可。

让gdb自动读取./.gdbinit
