Subject: [FFmpeg-devel] [OSS-Fuzz] Have you considered enabling memory sanitizer?
Date: Wed, 26 Jun 2024 21:07:42 +0200
Message-ID: <CABPLASRrX4VvgfYfui=MxiGkg7DQYOSf-UecMjuC8nmqAr3utg@mail.gmail.com> (raw)

Hi,

Like in the topic. I think it would be useful to enable MSAN on
OSS-Fuzz. We get some tiny issues and it would be probably good to
have them tracked upstream. All infra is here, so enabling it is as
simple as adding it to the project.yaml. Except libbz2.so and libz.so
would have to be built inline instead, looking at the build.sh, they
are prebuilt. The rest should just work (TM), but needs to be tested.
You can set an "experimental' flag to have it not create issues on
monorail, initially.

Thanks,
Kacper
