> (In contrast to the latter, it's disabled with `-O1`, which worked for
me, but only in conjunction with the latter, i.e. `-O1 -fno-delete-null-
pointer-checks`, IIRC, cf. #20738 comment 6.)
With just `-fno-strict-overflow"` added to (just) `CXXFLAGS`, `./sage
--singular` immediately segfault for me.
