If you want to improve this, its welcome! note though this enables fuzzer+address+undefined theres also memory which cannot be enabled at the same time it seems (at least not when i tried) and needs a seperate build. so toolchain=3Dclang-fuzz is a little to limited we need fuzz+address+undefined and fuzz+memory at least or something liek t= hat thx [...] --=20 Michael GnuPG fingerprint: 9FF2128B147EF6730BADF133611EC787040B0FAB The worst form of inequality is to try to make unequal things equal. -- Aristotle --C0gMXX03pFsIClwS Content-Type: application/pgp-signature; name="signature.asc" -----BEGIN PGP SIGNATURE----- iF0EABEKAB0WIQSf8hKLFH72cwut8TNhHseHBAsPqwUCaHeoegAKCRBhHseHBAsP q14/AKCSVeRgWp4RWyjnrqHkjwph/TtNDACeKJcvQypv40RaFSNnYjcUei3kFcA= =ibDy -----END PGP SIGNATURE----- --C0gMXX03pFsIClwS-- --===============5984819612670285358== Content-Type: text/plain; charset="us-ascii" MIME-Version: 1.0 Content-Transfer-Encoding: 7bit Content-Disposition: inline _______________________________________________ ffmpeg-devel mailing list ffmpeg-devel@ffmpeg.org https://ffmpeg.org/mailman/listinfo/ffmpeg-devel To unsubscribe, visit link above, or email ffmpeg-devel-request@ffmpeg.org with subject "unsubscribe". --===============5984819612670285358==--
