Maysam Yabandeh 1fb6805527 Fix snprintf buffer overflow bug (#4465)
Summary:
The contract of snprintf says that it returns "The number of characters that would have been written if n had been sufficiently large" http://www.cplusplus.com/reference/cstdio/snprintf/
The existing code however was assuming that the return value is the actual number of written bytes and uses that to reposition the starting point on the next call to snprintf. This leads to buffer overflow when the last call to snprintf has filled up the buffer.
