Description Florian Weimer 2013-11-29 15:32:01 UTC
xsnprintf makes fortify protection ineffect.  It should be an inline function or a #define.

The function does not guard against negative or oversized return values, and callers assume that it always returns values in the range [0, size - 1] (see arguments.c:args_print() for an
example).
