Debugging dynamic memory with Valgrind
Take a look at this video.
Valgrind is already installed on the server. A file containing the
test1 function from the video is located at
/public/examples/valgrind/val_test.c on the server. If you copy it and compile with
gcc -o val_test -Wall -g val_test.c, you can run valgrind on it with
valgrind ./val_test and see the same errors from the video. Then make the corrections from the video, recompile, and rerun
valgrind ./val_test to see that the errors have been resolved.
