How to Insert breakpoint while gdb is executing

Question

I want to add some breakpoints while gdb is executing . How to suspend running gdb and insert breakpoint and continue from there . I tried ctrl+z , it kills the gdb process.

Answer 1

Ctrl-c breaks the execution of your program within gdb, and allows you to insert any breakpoints you like. Stopping is very well explained in the manual. I would suggest you read it, it gives you an huge advantage when debugging.
