Data Breakpoints in Visual Studio Code
summary
Demo uses a simple Fibonacci program that prints the first 15 terms and shows three concrete breakpoint types in VS Code when debugging with GDB: a line breakpoint, a conditional breakpoint that stops when i == 5, and a data breakpoint on nextTerm (4 bytes) which pauses whenever that memory changes. A data breakpoint on unchanged n does not fire. Attempting a data breakpoint on string MSG (32 bytes) fails with "Value does not fall within the expected range parameter size", due to hardware register limits. Use a backtick to run GDB commands like info breakpoints in the debug console.
