+  * Function    :  zalloc_or_die
+  *
+  * Description :  zalloc wrapper that either succeeds or causes
+  *                program termination.
+  *
+  *                Useful in situations were the string length is
+  *                "small" and zalloc() failures couldn't be handled
+  *                better anyway. In case of debug builds, failures
+  *                trigger an assert().
+  *
+  * Parameters  :
+  *          1  :  size = Size of memory chunk to return.
+  *
+  * Returns     :  Pointer to newly malloc'd memory chunk.
