+Subject: [PATCH 3/5] Replace snprintf with strncpy at some places to avoid
+ truncation
+
+In gcc7 there are some building errors like:
+directive output may be truncated writing up to 31 bytes into a region of size 24
+snprintf(str, MPB_SIG_LEN, %s, mpb->sig);
+
+It just need to copy one string to target. So use strncpy to replace it.
+
+For this line code: snprintf(str, MPB_SIG_LEN, %s, mpb->sig);
+Because mpb->sig has the content of version after magic, so
+it's better to use strncpy to replace snprintf too.
