Assuming that the failure happens more than once every few thousand test runs, here’s a handy shell snippet:
while prove -bv t/MaxMind/DB/Writer/Tree-freeze-thaw.t ; do reset; done
This will run the relevant test in a loop over and over, stopping at the first failure. The reset in between each run makes it easy to hit Ctrl-Up in the terminal and go to the beginning of the test run that failed, rather than having a monster scrollback buffer.
