bool "Enable safe version of sprintf()"
help
Since sprintf() can overflow its buffer, it is common to use
snprintf() instead, which knows the buffer size and can avoid
overflow. However, this does increase code size slightly (for
Thumb-2, about 420 bytes). Enable this option for safety when
using sprintf() with data you do not control.
