Hello,

We are using 2.6.16.46-0.12-default kernel.
And GNU gdb 6.6 version.

We are getting following error while using gdb for core file.

I am not so familiar with the gdb application so I might be missing something very obvious. Please suggest.

Thanx,

it mentiones prelinking, this is a process that prepares c++ programs linking information which allows them to start faster.

http://en.wikipedia.org/wiki/Prelink

see randomization section of the article, might be the cause.
