gdb watch

Summary

GDB can be used to set watchpoints, which are used to detect errors in programs. Watchpoints are set by single-stepping the program and testing the variable's value each time, which is hundreds of times slower than normal execution. 1 2 There are different types of watchpoints, such as hardware watchpoints, location-based watchpoints, and memory corruption watchpoints. 3 Tips and tricks for using watchpoints in GDB include using a refactoring tool to clean up memory leaks, using a watchpoint with a refactoring tool, and using a watchpoint with a pointer to check if a pointer is overwritten. 4

Summary GDB does software watchpointing by single-stepping your program and testing the variable’s value each time, which is hundreds of times slower than normal execution. (But this may still be worth it, to catch errors where you have no clue what part of your program is the culprit.)
