--- Comment #11 from Dan Kegel dank@kegel.com 2011-05-20 17:33:49 CDT --- http://www.in-ulm.de/~mascheck/various/argmax/ has an awesome summary of the limit on commandline length on various unixes. In Linux-2.6.33 and later, the limit was raised significantly (to "1/4 of the stack space"). (This patch came from Google (Hi Ollie!).)
It's possible that on modern linux, you wouldn't run into this problem even without builtin printf. If that's the case, then IMHO it's still worth filing an enhancement request with FreeBSD.
