"gdb program core.11230"
is the actual format of loading core to gdb. But I don't have 'program' binary. instead I have separate debug file along with core. So I am loading .debug file instead of binary as
"gdb coredump.debug coredump_core.dump"
This GDB was configured as "x86_64-redhat-linux-gnu".

Core was generated by `./coredump'.

It won't show me the exact line number and source code file while debugging in GDB. It is not the case with normal debugging with binary and core.
also I don't have source file. I have access only to core dump and separate debug files.
What am I doing wrong. Please some experts suggest?
