+Subject: [PATCH] Fix the stack buffer overflow issue
+
+strlen() could returns 0. Without a conditional check for len,
+accessing S_ pointer with len - 1 may causes a stack buffer overflow.
+
+AddressSanitizer reports this like:
+==1219243==ERROR: AddressSanitizer: stack-buffer-overflow on address 0x7ffdce043c1f at pc 0x000000403547 bp 0x7ffdce0
