Details:

Long running invocations of find, e.g. as part of update-locatedb, grow their
allocated memory beyond all bounds. On my system (NixOS), I have regularly
observed it to take more than 12G of RES memory.

This bug was originally reported to the ubuntu tracker
(https://bugs.launchpad.net/ubuntu/+source/findutils/+bug/1364492) and the
patch that was posted there by Juan Carlos Cordero González
(https://launchpadlibrarian.net/304000719/find_bug.patch) fixed the condition
for me.
