To enable the address sanitizer (ASan) and the undefined behavior sanitizer (UBSan), add `-Db_sanitize=address,undefined` to the `meson` command.
In order to be able to collect core dumps on ASan failures (to inspect variable state at the point of failure, for instance), you must specify `ASAN_OPTIONS=abort_on_error=1:disable_coredump=0:unmap_shadow_on_exit=1` in the environment that you launch `sway` in.
When pulling from the Sway repo, remember to also pull from the wlroots repo.
