We are fuzzing a tool named STG
(https://android.googlesource.com/platform/external/stg/+/refs/heads/master
),
which is using libdw and libdwfl from elfutils. And it already has support
for
execution through libFuzzer:
https://android.googlesource.com/platform/external/stg/+/refs/heads/master/fuzz/

The problem is in building infrastructure. STG as fuzzing target is built
inside
Google using internal build and fuzzing infrastructure, but in principle it
does
the same thing as OSS-Fuzz. An AOSP version of STG is built using Android
build
system, which doesn't support the same simplicity of building with
libFuzzer and
sanitizers. So it needs some work to integrate STG into OSS-Fuzz.
