[arm-gnu] Core File seems to be corrupted

["Balaji Kani -X (balkani - WIPRO at Cisco)" <balkani@xxxxxxxxx>]

Hi all,

 

    I have built an application to run on ARM processor and when ever my
application crashes, I get the core file.

 

    But the issue is that the core file seems to be corrupted. I get the
following when I issue "bt" or "where" command.

    It does not show the function names properly.

 

Cannot access memory at address 0x400256b0

(gdb) bt

#0  0x402b39d8 in ?? ()

#1  0x40299004 in ?? ()

#2  0x40299004 in ?? ()

Previous frame identical to this frame (corrupt stack?)

 

    I have built the application with -g option still I get this issue
consistently. 

+CFLAGS += -g -O2

+CFLAGS += -D_DEBUG

 

     Could you please help me with this regard ?
