Error when lifting.

I got this error. I have attached the files for you.

References to __stack_chk_fail and use of operand %fs:0x28 - for what appears to be stack-guard value - in the binary provided seems to indicate that the binary is built with stack protection enabled.

I have not yet added support to abstract usage of the segment register %fs (or %gs) to the tool. So, the binary provided cannot be raised due to that limitation, at present. Any contribution to support this ability is welcome.
