Provided are techniques for identification and handling of nested breakpoints during debug session. Program code having functions, nested breakpoints, and an indication of whether each of the breakpoints is likely to be reached is displayed, in a visualization. In response to receiving input that selects a function from the functions, a call graph is displayed for the functions in the program code to enable viewing where each of the nested breakpoints is located in the program code with reference to the functions. An option to disable a nested breakpoint of the nested breakpoints for a current execution of the program code is provided. In response to receiving input that selects the option, the nested breakpoint is disabled.
