--- Comment #6 from H.J. Lu <hjl.tools at gmail dot com> ---
Large model thunk with PIC never worked.  GCC 4.8 generates:

_ZThn8_N12ScriptString12CreateStringEPKc:
.LFB1:
    .cfi_startproc
    subq    $8, %rdi
    movabsq    $.LTHUNK0@GOTOFF, %r10
    addq    %rbx, %r10
    jmp    *%r10
    .cfi_endproc


It never sets up GOT base pointer.
