Can I Debug Release Code?

[@cipherxen2]

I really like the strip command. Using it for years now.

[@RmFrZQ]

I think you forgot to mention on how to use external debugging symbols, if they are available. They could be available for some libraries and calls used in the program, and they should make assembly debugging more sane and productive.

Helpful video, thanks for sharing this neat trick!

Thanks, a lot of good ideas!

Is it possible to access callstack inside any function? Or can we know caller of a function?

[@qwertyqwerty-jp8pr]

during program execution, yes. the caller return address is pushed onto the stack so just check the stack memory to see where the function is called

What toolset would you suggest to an experienced developer, who 's willing to make a transition into low-level coding, so that the given toolset would have a high demand on a job market ?

[@JacobSorber]

I would need more details on where you are (what experience you have) and where you are trying to get. Are you trying to get into embedded systems stuff? OS-level work on laptop/desktop/server-class machines? Phones? Those decisions constrain the set of tools a bit. If you're not sure, I would just stick with gcc or clang (and their associated tools) and try to learn as much about how the underlying software layers work. My experience has been that most of the different tools operate similarly.

@@JacobSorber My main goal is to get away from web development. Most of my experience is java backend, some j2me, a tiny bit of javascript, but since I was a student, I was always curious about x86 assembly and machine codes. I don't mind get into Windows or Linux desktop apps, maybe some system programming for PC, drivers. Some kind of position to work with full blown OS, I guess, as opposed to exotic world of microcontrollers etc. For example, is it better to invest my time into WinDbg or GDB ?

Hey could you make a video on multi pipe commands in C ? for example if you have "command1 | command2 | command3 | ...." , how to handle all those fd's the right way with dup/dup2/pipe/close/execve/fork

[@JacobSorber]

I'll add it to the list and see what I can do.

How can we debug a string. basically checking strings just like we check Integer value

[@JacobSorber]

The print command in gdb works with strings (char *), too. If you're having issues with string corruption and things not being properly null-terminated, check out my video on examining memory in gdb.
