+       Prohibit LAG following TEMPORARY.  This both matches SPSS behavior
+       and fixes a bug: we saved the cases for LAG before TEMPORARY but
+       allowed access to variables created afterward anyhow (which could
+       cause a segfault).
+
+       * generate.pl: Parse "perm_only" flag on operations.
+
+       * operations.def: Add "perm_only" flag to LAG operations.
+
+       * parse.c: Disallow OPF_PERM_ONLY operations after TEMPORARY.
+
+       * parse.inc.pl: Output OPF_PERM_ONLY flag for "perm_only"
+       operations.
+
+       * private.h: Add OPF_PERM_ONLY flag.
