I can burrow down through file->variables->next->next->next etc... 

(dbx) print *file->variables
*file->variables = {
    (*file->variables).next = 0x2bba4a0
    (*file->variables).set = 0x2b84388
}
(dbx) print *file->variables->next
*file->variables->next = {
    (*file->variables->next).next = 0x85670
    (*file->variables->next).set = 0x2bb9ce0
}
(dbx) print *file->variables->next->next
*file->variables->next->next = {
    (*file->variables->next->next).next = 0x1dbf868
    (*file->variables->next->next).set = 0x8aeb0
}
(dbx) print *file->variables->next->next->next
*file->variables->next->next->next = {
    (*file->variables->next->next->next).next = 0x85670
    (*file->variables->next->next->next).set = 0xa7c6b0
}

Is that any use to you?
