+ * Function    :  strdup_or_die
+ *
+ * Description :  strdup wrapper that either succeeds or causes
+ *                program termination.
+ *
+ *                Useful in situations were the string length is
+ *                "small" and strdup() failures couldn't be handled
+ *                better anyway. In case of debug builds, failures
+ *                trigger an assert().
+ *
+ * Parameters  :
+ *          1  :  str = String to duplicate
+ *
+ * Returns     :  Pointer to newly strdup'd copy of the string.
+ *
