>Description:
Since I've already done a send-pr for NetBSD that explains the problem,
I'll just post a link:

http://www.NetBSD.org/cgi-bin/query-pr-single.pl?number=16483

Remarkably, the commit log for snprintf.c indicates this problem (or an extremely close approximation; I was leaking in __smakebuf as well) was reported against 4.2, fixed, the PR (#26044) closed, and then unfixed.

>How-To-Repeat:
      
>Fix:
I worked around the problem using a 1-character buffer.
