After a Merge operation, the statistics for number of samples generated using Expand must be corrected, and the correction can in fact be negative. However, a bug was introduced in https://codereview.webrtc.org/1230503003 which uses a size_t to represent the correction, which leads to wrap-around of the negative value. This is not a problem in itself, since this value is added to another size_t, with the effect that the desired subtraction happens anyway. The actual problem arises if the statistics are polled/reset before a subtraction happens -- that is, between an Expand and a Merge operation. This will lead to an actual wrap-around of the stats value, and large expand_rate (16384) is reported.
