These types of errors are tricky, as they can provide little debugging information, and tracing the observed problem back to underlying root cause can be challenging. valgrind is here to help! memory errors vs. memory leaks. valgrind reports two types of issues: memory errors and memory leaks. when a program dynamically allocates memory and. Running a program under valgrind. like the debugger, valgrind runs on your executable, so be sure you have compiled an up to date copy of your program. running under valgrind can be as simple as just prefixing the program command like this: valgrind . mywhich p " usr bin: usr sbin" ls. which starts up valgrind and runs the program inside of it.

When a segmentation fault is raised, valgrind will print a stack trace: a listing of all the functions that were called up until the fault, and which lines they were on (if you passed the g option when compiling). the most familiar example of a segfault happens when you attempt to dereference a null pointer: int*i = null; *i = 3;.
