What do you like best?
Breaking at a function (break points)
Check the call stack of a function (backtrace)
Put a read/write watchpoint for a variable/object (memory corruption)
Dumping memory
What do you dislike?
Live display of code (l command) , there is still inconsistency with the line and variables. TUI extensions help though.
Watchpoints make the code execution extremely slow. Can't even think about putting a watch point while kernel debug.
Kernel debugging with GDB (kgdb) is tedious and needs a lot of setup efforts. Also has lack of support here.
Recommendations to others considering the product:
- It's one of the best debuggers available. Very powerful and handy.
- It's available for wide range of platforms and architectures.
- Do spend some time with it initially, its worth every penny.
- If you are not comfortable with non-gui interface try ugdb/gdbtui etc
What problems are you solving with the product? What benefits have you realized?
Day to day programming bugs, crashes, NULL pointers related errors. I also use GDB to print variables (instead of adding prints and recompiling) and inspect the stack. I also enjoy tracking a unknown code with backtrace, the call stack dump helps me to understand the code flow faster.
