loading core symbols for debugging purpose

Hello, My goal is to set breakpoint at some instruction address in the core process to trace its execution. To achieve this, I use this command in gdb. *add-symbol-file <filename> <load address>*

But I cannot access the core load address.

*objdump -h debug/core-nova.o *yields LMA for the .text section : 0x0000000000000000 And the ld-nova.lib.so does not help too.

Can someone point me, in order to trace the core process execution, at which address to load the core symbols file?

Thanks,
