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

(gdb) call debug_rtx (rtl)

(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 ])
