3Why do you want to inspect the vtable? It is normally considered an implementation the compiler uses for virtual functions. – Anders Abel Mar 27 '10 at 14:55

if using ddd front-end is an option, it automates a lot of the C++ objects display. – PypeBros Sep 03 '10 at 11:26

Did you try set print object on ?
(gdb) help set print object
Set printing of object's derived type based on vtable info.

BTW, in lldb this is equivalent to "settings set target.prefer-dynamic run-target". I'm answering this just because gdb is no longer part of Xcode. – kakyo Jul 11 '14 at 20:06

Sorry, it should have been "settings set target.prefer-dynamic-value run-target" – kakyo Jul 11 '14 at 20:59

Thank you. That's the answer - so glad you posted this all the way in 2010! – Chris Sherlock Jan 15 '15 at 15:54

If you have a sufficiently new version of gdb, you may want to look at the "info vtbl" command (or perhaps it is called "info vtable"; my own version of gdb is not sufficiently new, and so I cannot test the feature out myself).
I only noticed the feature when googling for an answer to this question and I noticed posts to the gdb mailing list circa 2012, notably this one from March 2012:
