Message-ID: <OFD216B7C7.FF53B16F-ON4825738D.0007D79C-4825738D.0007E87C@sunnorth.com.cn> (raw)

Dear Joel:

        I am using GDB6.1.1

        GDB did not stop at the wrong location now, but I have see that 
the function:

        find_pc_line_pc_range (stop_pc, &step_range_start, 
&step_range_end) didn`t work correctly.

       when stop_pc is 0x8000035 the returned value of step_range_start 
and step_range_end is

        0x800003c5 and 0x800003cb

        but they should be

        0x800003c5 and 0x800003cf


        I have found all these are because there is something wrong with 
the Dwarf2 .debug_line section. 
        Now every instruction has a entry in this section, maybe it should 
be every c statement.

        Cause I can not modify compiler or assembler now, So I want to 
know How can I solve this problem
        just within GDB.

        Thanks.
