+*** cc compile fsan
+Sanitisers are a blessing for C/C++. An additional runtime on top of
+the executable which catches stuff like undefined behaviour or memory
+leaks make it super easy to see where and how code is failing.
+However, by default, Emacs' compilation-mode doesn't understand the
+logs =fsanitize= makes so you usually have to manually deal with it
+yourself.
+
+Compilation mode uses regular expressions to figure out whether
+something is an error and how to navigate to the file where that error
+is located. So adding support for =-fsanitize= is as simple as making
+a regular expression which captures file names and digits
