VC's C++ exception handling on x64 is table-based but still powered by SEH. Debug into a throw and you'll see VC's _CxxThrowException() call Windows' RaiseException().

VC++ did move from SEH to something similar to table based unwinding,
but, AFAIK it is still quite different from DWARF tables format and
not compatible.
