The documentation for stdio says

"By default, fdevopen() as well as the floating-point versions of the printf
and scanf family require malloc()."
Looking at the version 1.4.5 source code for vfscanf and vfprintf, it appears
that the floating point buffers are local variables, and malloc is not used.
