Follow-up Comment #1, bug #62622 (project findutils): I noticed this a while ago but forgot to report it: https://github.com/sharkdp/argmax/issues/1#issuecomment-972035652 `xargs` is trying to find the real limit with binary search: https://git.savannah.gnu.org/cgit/findutils.git/tree/lib/buildcm

Follow-up Comment #1, bug #62621 (project findutils): Another thing: hypothetically, `xargs` could be built as a 32-bit binary, launching a 64-bit binary. In that case, `sizeof(void *)` is not enough, since `xargs` will think it's 4 while the kernel will think it's 8. __
