Unbalbe to gdb core file generted from customer machine on local host

[James C Chen]

Hi there,

Thanks for providing gdb support.

I created an executable binary (x86-64) on my local Linux server and let it
run on customer Linux server. Later on, my binary generated a core
file.  I tried to gdb the core file on my local Linux server, but I can not
get correct stack trace.

(gdb) bt full
#0  0x0000003a5d07288e in ?? ()

#8  0x0000000000000000 in ?? ()

But when I gdb the core file on customer server where the core file was
created, I am able to get correct stack trace.

Question, do I have to gdb the core file on the customer server to get
correct stack trace? Any way to gdb the core file on my local server?

Thanks you very much for any help.
