SEGV and ABRT by default cause a core dump, which may create a file, launch crash handlers, and so on. sanity-test has 21 processes that are expected to crash like this. Disable core dumps on them all. I counted 21 entries in coredumpctl list, while only 16 functions needed patching. After this patch no entries appear in coredumpctl list.
