title: gdb: No symbol "_v8_internal_Print_Object" in current context
body: <p>I want to compile v8 engine on my mac(10.14.6 mojave) and use gdb for debugging. So I do the step below.</p>
  <pre><code>tools/dev/v8gen.py x64.debug
  ninja -C out.gn/x64.debug d8
  </code></pre>
  <p>And I import the script(/path/to/v8/tools/gdbinit) to use 'job' command.</p>
  <p><strong>~/.gdbinit</strong>:</p>
  <pre><code>set startup-with-shell off
  source /Users/xxxx/pwndbg/gdbinit.py
  source ~/.gdbinit_v8
  source /Users/xxxx/v8/v8/tools/gdb-v8-support.py
  </code></pre>
  <p>And then I use</p>
  <pre><code>sudo gdb ./d8
  </code></pre>
  <p>When I input <code>job 0x284a9de0e361</code>
  It returns <code>No symbol &quot;_v8_internal_Print_Object&quot; in current context.</code>It seems that this function should be declared by v8, but I can’t use it. Did I miss what configuration caused this interface not to be exposed? Please help me if anyone know what happens. Thanks a lot！</p>
