--- Comment #2 from Richard Biener <rguenth at gcc dot gnu.org> ---
The hard limit is there to make compiling possible in some cases. Btw,
santizing makes your "small" testcase quite large.
It's also of the usual repeat-many-similiar-things-in-one-functions cases
where var-tracking runs into quadraticnesses.
Confirmed with -O2 -g -fsanitize={undefined,address} (only need either, not
both)
