Subject: [PATCH 25/29] 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")
