Once it's merged and reaches ClusterFuzz OSS-Fuzz should close the issue. > Note that we also recently got support for --enable-sanitize-memory but > that needs a bit of setup and only works with the clang compiler. See > https://inbox.sourceware.org/elfutils-devel/6e576e707fa3da14f4e9045cbf53ba887823a543.camel@linux.ibm.com/T/ Thanks! It helped to pinpoint the issue. I think it would be better if it was possible to turn off --no-undefined separately to make it easier to build elfutils on OSS-Fuzz (where I can't pass `--enable-sanitize-*`) and avoid build failures like that going forward. It was discussed in https://sourceware.org/pipermail/elfutils-devel/2021q4/004418.html but didn't go anywhere though. Thanks, Evgeny Vereshchagin
