--- Comment #3 from Bernd Edlinger <bernd.edlinger at hotmail dot de> ---
The test case is interesting, as it contains an
empty inlined subroutine ptr::get() :

 <2><11c>: Abbrev Number: 17 (DW_TAG_inlined_subroutine)
    <11d>   DW_AT_abstract_origin: <0x18a>
    <121>   DW_AT_entry_pc    : 0x40113f
    <129>   DW_AT_GNU_entry_view: 2
    <12a>   DW_AT_low_pc      : 0x40113f
    <132>   DW_AT_high_pc     : 0x0
    <13a>   DW_AT_call_file   : 1
    <13b>   DW_AT_call_line   : 11
    <13c>   DW_AT_call_column : 18
    <13d>   DW_AT_sibling     : <0x14f>

The call instruction is immediately after this empty inline block,
when the call stack is printed, the line table finds
the stmt line 3 followed by non-stmt line 11.
My patch modifies the logic in find_pc_sect_line if a line at the
end of the subroutine is found, but the PC is larger than that,
the non-stmt line 11 following the subroutine is preferred.
