Thanks. How did you verify it's an optimization?
Optimization is that there is no superfluous copying into string.
The to_string functions always pass at least __n=16 to __to_xstring, which is larger than the SSO buffer in std::__cxx11::string, and so forces a memory allocation.
I didn't think about this... -- Regards, niXman ___________________________________________________ C++ for Bitcoins: github.com/niXman
