Question about bugs in gcc in (v)(s)(n)printf() functions

[Jamaika1]

Were the bugs fixed in gcc 15.x.x (v)(s)(n)printf()?

matroskaenc.c:3349:79: warning: '%012.9f' directive output may be truncated writing between 12 and 320 bytes into a region of size between 8 and 14 [-Wformat-truncation=]
 3349 |                 snprintf(duration_string, sizeof(duration_string), "%02d:%02d:%012.9f",
      |                                                                               ^~~~~~~

Which form is correct?

#ifdef __MINGW32__
char duration_string[333] = "";
#else
char duration_string[DURATION_STRING_LENGTH + 1] = "";
#endif

or

#ifdef __MINGW32__
__mingw_snprintf(duration_string, sizeof(duration_string), "%02d:%02d:%012.9f",
#else
snprintf(duration_string, sizeof(duration_string), "%02d:%02d:%012.9f",
#endif
