gdb error while running preprocessed file in gcc directory.

Hello,
I am Krishna Narayanan,second year undergraduate interested in
compiler related domain.I am trying to run a preprocessed file .i with
the command "gcc 93432.i -wrapper gdb,--arg" which gives me the below
warning and then a fix to remove this warning by setting an
add-auto-load-safe-path,as given I added the said path in the .gdbinit
in the home directory but that instead gave me a gdb error.I am not
able to resolve this issue,I am doing this on the gcc 11.2.0 build.

warning: File "/home/krishna/latest/gcc/.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/krishna/latest/gcc/.gdbinit
line to your configuration file "/home/krishna/.gdbinit".
To completely disable this security protection add
    set auto-load safe-path /
line to your configuration file "/home/krishna/.gdbinit".

On adding the add-auto-load-safe-path in the home directory(.gdbinit)
,it gives me this below error after running the same command in the
gcc build directory "gcc 93432.i -wrapper gdb,--arg"
