+/* redisassert.c -- Implement the default _serverAssert and _serverPanic which 
+ * simply print stack trace to standard error stream.
+ * 
+ * This file is shared by those modules that try to print some logs about stack trace 
+ * but don't have their own implementations of functions in redisassert.h.
