ulimit -v is generally not supported with ASAN, giving errors like: "ReserveShadowMemoryRange failed while trying to map 0x... bytes. Perhaps you're using ulimit -v" * tests/cp/link-heap.sh: Mention ASAN as a possible reason for skipping. * tests/csplit/csplit-heap.sh: Likewise. * tests/cut/cut-huge-range.sh: Likewise. * tests/dd/no-allocate.sh: Likewise. * tests/printf/printf-surprise.sh: Likewise. * tests/rm/many-dir-entries-vs-OOM.sh: Likewise. * tests/head/head-c.sh: Only skip the part of the test needing ulimit. * tests/split/line-bytes.sh: Likewise.
