I was trying to *print out the `v8::Local` object details,*   with either 
of `v8/tools/gdbinit` and `v8/tools/lldb_commands.py` helper scripts, I 
just got "*Empty Line*" OR *"syntax error"*. Is there anything I've missed?

Most of configurations are from official embed tutorial 
(https://v8.dev/docs/embed), without any single line of modification. Here 
are some details:

*Source Branch:*  "main"    (2022/01/18)
*Build Configuration:*  "x64.release.sample"
*Program:*  "v8/samples/hello-world.cc"
*Platform:*  "Ubuntu18.04 + GDB10"* /* "macOS 10.14 + LLDB11"

*GDB ouput:        * (ubuntu18.04)
*-----------------------------------------------------------------------------*
*###  Compile* & Link
*$ *g++ -I. -Iinclude samples/hello-world.cc -o hello_world -lv8_monolith 
-ldl -Lout.gn/x64.release.sample/obj/ -pthread -std=c++14 
-DV8_COMPRESS_POINTERS -g

*###  Debug*
*$ *gdb -x tools/gdbinit ./hello_world

*(gdb) *p result
$1 = {val_ = 0x55d4f7a35408}
*(gdb) *jlh result
A syntax error in expression, near `)(result).val_))'.
