[arm-gnu] Stack seems to be corrupted

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

Hi all,

    I'm using Sourcery G++ Lite 2008q3-72 version of the ARM compiler
and while executing my code, I got an core file.
    But when I tried to decode the crash, I found that it is pointing to
libc.so.6.

    Is this a known error? Or is that stack is corrupted ? If stack is
corrupted, is there a way to debug the issue?

    Can someone could throw some light on this?

    Thanks in advance.

Regards, Balaji
