------- Comment #4 from ubizjak at gmail dot com  2009-08-22 13:51 -------
Patched gcc:

bar:
        pushl   %ebp
        movl    %esp, %ebp
        pushl   %ebx
        subl    $20, %esp
        movl    8(%ebp), %ebx
        movl    %ebx, (%esp)
        call    foo
        subl    $4, %esp
        movl    %ebx, 8(%ebp)
        movl    (%ebx), %eax
        movl    -4(%ebp), %ebx
        leave
        jmp     *%eax
