Oops. While this patch fixed the behaviour on mingw 5, it broke it on mingw 13 (with -D__USE_MINGW_ANSI_STDIO=0). This patch should now fix it for both: 2025-09-16 Bruno Haible <[email protected]> strerror_r-posix: Fix truncation code (regression today). * lib/strerror_r.c (strerror_r): Fix use of snprintf again. diff --git a/lib/strerror_r.c b/lib/strerror_r.c index b67684ebe6..1e6974e327 100644 --- a/lib/strerror_r.c +++ b/lib/strerror_r.c @@ -450,9 +450,9 @@ strerror_r (int errnum, char *buf, size_t buflen) #endif #if defined __HAIKU__ /* For consistency with perror(). */ - snprintf (buf, buflen - 1, "Unknown Application Error (%d)", errnum); + snprintf (buf, buflen, "Unknown Application Error (%d)", errnum); #else - snprintf (buf, buflen - 1, "Unknown error %d", errnum); + snprintf (buf, buflen, "Unknown error %d", errnum); #endif buf[buflen - 1] = '\0'; }
