Can I analyze a program s core dump file with GDB when it has command-line parameters

Question

The following is what my program operates like.

exe -p param1 -i param2 -o param3

It crashed and generated a core dump file, core.pid.

What I want to do is analyze the core dump file by doing this.

gdb ./exe -p param1 -i param2 -o param3 core.pid

But the GDB recognizes parameters of the EXE file as GDB's input.

How can I analyze a core dump file in this situation?

Answer 1

You can simply use of GDB, to debug coredump files:

gdb <executable_path> <coredump_file_path>

Coredump file for a process gets created, as "core.pid" file. After you get inside the gdb-prompt;

...
(gdb) where

This will get you with the information, of the stack, where you can analyse the cause of the crash/fault.

Hope this helps you!
