Split out from #25096, where @hyangah wrote:

With the default memprofile sampling rate, however, the results look different. The results are different from the results with -memprofilerate=1, too. The order in the top15 list varies a lot. This seems to me errors from sampling-based estimation, not the bug the original report suggested.

This is an issue to investigate that.
