+Subject: [PATCH] Call va_end after va_copy in json_vsprintf
+
+As said in man doc:
+ "Each invocation of va_copy() must be matched by a corresponding
+ invocation of va_end() in the same function."
+
+va_copy may alloc memory in some system, it's necessay to free it by
+va_end.
+
+Fixes: efe6c7b3f2b3 ("Add json_sprintf and json_vsprintf")

+Subject: [PATCH] Deal with warnings under gcc 8.
+
+Recent versions of gcc have introduced compiler warnings for string
+operations that could be truncated. This caused problems with -Werror.
+src/error.c used strncpy to write "..." to a string, but skipped writing
+the NUL terminator. Switch this to use memcpy. src/load.c produced
+warnings from snprintf writing error strings that could be truncated.
+Added code to autotools build to detect `-Wno-format-truncation', add it
+to AM_CFLAGS if supported.
