It's not a new ABI in the sense that you mean.  It's a new ABI version
- gcc now has a command line switch for incompatible bug-fixes to the
existing ABI.  The only change between -fabi-version=1 and
-fabi-version=2 that will affect GDB is probably this one, which moves
virtual destructors to another location in the vtable.

This is still the "Itanium C++ ABI".  It's just a little closer to the
published document than it used to be :)  I don't remember it being
called ABI 2 - if anything, it was called the v3 ABI, for GCC 3.
