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

Thanks!

This is a straightforward sanity check working as intended:

  template <typename T>
  static size_t QuantizedSize(size_t count) {
    CHECK_LE(count, MaxElementCountInBackingStore<T>());
    return WTF::Partitions::BufferPartition()->ActualSize(count * sizeof(T));
  }

Labels: Needs-Feedback
ClusterFuzz testcase 5193552276226048 is still reproducing on tip-of-tree build (trunk).

If this testcase was not reproducible locally or unworkable, ignore this notification and we will file another bug soon with hopefully a better and workable testcase.

Otherwise, if this is not intended to be fixed (e.g. this is an intentional crash), please add ClusterFuzz-Ignore label to prevent future bug filing with similar crash stacktrace.
