Shouldn't vt_get_decl_and_offset handle:

vt_get_decl_and_offset (rtl=0x7ffff1abad60, declp=0x7fffffffda00, 
    offsetp=0x7fffffffda08)
    at /export/gnu/import/git/gcc/gcc/var-tracking.c:9275
9275      if (REG_P (rtl))
(gdb) call debug_rtx (rtl)
(parallel:TI [
        (expr_list:REG_DEP_TRUE (reg:DI 5 di [ f ])
            (const_int 0 [0]))
        (expr_list:REG_DEP_TRUE (reg:DI 4 si [ f+8 ])
            (const_int 8 [0x8]))
    ])
