Why don't you simply use the strstream class ? It's much more elegant (i.e. it
allocates it's own memory as needed) than LEDA's printf-like Constructors, and 
i think it's pretty standard in the C++ world.

I've just looked over the code in _string.cc , it's the most ugly stuff I've
seen so far (and i've produced many ugly things in my lifetime ...).  I think
working with fixed sized arrays for creation/formatting is generally a stupid
idea. They've got so many beautiful data structures, why don't they simply keep a
list of fixed size buffers and cat them together when reading/construction is
complete ?

Besides this, i like the LEDA data types very much, especially the list/graph
stuff. They've just better put some more work into the basics & into Makefile/
configuration stuff (when i get a LEDA version, i don't even try to compile with
their provided Makefiles, i throw them away just after unpacking ... )
