What {fmt} library version do you use and what was the exception message?

[Joe-Yeh]

1. {{fmt}} library version ==> #define FMT_VERSION 50201
2. exception point ==> in format.h line 1073 => return internal::copy_str(buffer, buffer + num_digits, out);
3. exception data ==> Run-Time Check Failure Compiling errors VC2010 , QT4.8 #2 - Stack around the variable 'buffer' was corrupted. occurred
4. seems allocated working buffer is not enough.
