buffer[3] = '\0';

Null character is written at buf[3] for zero.
If we provide uninitialized buffer, buf[1] and buf[2] contains garbage and printf/cout does not work well when we don't use returned the number of string length(e.g. directly construct std::string from char[] buffer)

Possible fix would be

buffer[0] = '0';
buffer[1] = '\0';

?

Oh yes, you're certainly right, my bad. That's due to one of the previous changes in 3742c9b. Will fix it now.

Many thanks for your report!
