Fuzzer test was configured in a wrong way in https://webrtc-review.googlesource.com/c/src/+/129768 This fixes it (verified locally on libfuzzer MSAN and ASAN). Bug: webrtc:8649, chromium:950813 Change-Id: I52647bb12c4c412252cdcd931c9e210606bdb12d Reviewed-on: https://webrtc-review.googlesource.com/c/src/+/132009 Commit-Queue: Alex Loiko <aleloi@webrtc.org> Reviewed-by: Sam Zackrisson <saza@webrtc.org> Cr-Commit-Position: refs/heads/master@{#27516}
