The comment a few lines above says: // The filter can only cause overflow (in the w16 output variable) // if more than 4 consecutive input numbers are of maximum value and // has the the same sign as the impulse responses first taps. // First 6 taps of the impulse response: // 0.6399 0.5905 -0.3779 0.2418 -0.1547 0.0990 The original authors thought of this and didn't deem it important. Setting P3.

Unable to find actual suspect through code search and also observing no CL's under regression range, hence adding appropriate label and requesting someone from dev team to look in to this issue. Thanks!

kkaluri@, c#2 took care of the triaging effort here.

ClusterFuzz testcase 6391336666923008 appears to be flaky, updating reproducibility label.

Please ignore the last comment about testcase being unreproducible. The testcase is still reproducible. This happened due to a code refactoring on ClusterFuzz side, and the underlying root cause is now fixed. Resetting the label back to Reproducible. Sorry about the inconvenience caused from these incorrect notifications.
