Hi,Jochen,
Thanks for replying.When I used the command as for you,but It shown me

How to solve it? (the new address is because I'd re-run the same commands
.So it gives me the new allocated address.)
:D
(lldb) p *(v8::internal::Script)**0x000055555562b068
error: indirection requires pointer operand ('long' invalid)
