I get a testsuite failure for this test on Linux/x86-64 in 64-bit:
  g++.dg/abi/thunk4.C scan-assembler .weak\t_ZThn4_N7Derived3FooEv

The file contains:
        .weak   _ZThn8_N7Derived3FooEv
        .type   _ZThn8_N7Derived3FooEv, @function

I think you have to adopt both thunk3.C and thunk4.C for 64-bit hosts,

Andreas
