On compilation of redis, HWASAN OOMS, with RAM steadily but quickly increasing
until oom_reaper is called.

To replicate:
1. git clone --depth 1 --branch 6.0.9 <https://github.com/redis/redis.git
2. cd redis
3. make CC=clang CXX=clang++ CFLAGS="-fsanitize=hwaddress -fno-omit-frame-
pointer" LDFLAGS="-fsanitize=hwaddress" MALLOC=libc

Environment (in QEMU):
Operating System: openSUSE Tumbleweed 20201108 JeOS
Kernel Version (custom built): 5.10-rc3

Other Notes:
The balooning RAM usage always happens after "CC redis-benchmark.o" is
outputted.
