The root of the problem is that the printf() formatting in the msvcrt.dll now disables "%n" support by default. This was initially added in msvcrt8.dll and later and was apparently later backported to the msvcrt.dll on Win7 (and likely Vista) but not on XP. MinGW builds use the msvcrt.dll by default. Smartd calls _set_printf_count_output(1) only for MSVC builds. Use of "%n" should be avoided.
