Not obvious. Large amount of automatic variables (include 40-bytes
buffer for floats) produces very boatable code. The reason is 63-bytes
limit of index in 'ldd/std' operation.
And I shall add, that another version of 'printf' (bug #11820 -->
patch #3851) does not use 'malloc'. Buffer for float is very small
and also stack usage decreases considerable.
