+Subject: [PATCH] Fixed bug: invalid 'oldpc' when returning to a function
+
+The field 'L->oldpc' is not always updated when control returns to a
+function; an invalid value can seg. fault when computing 'changedline'.
+(One example is an error in a finalizer; control can return to
+'luaV_execute' without executing 'luaD_poscall'.) Instead of trying to
+fix all possible corner cases, it seems safer to be resilient to invalid
+values for 'oldpc'. Valid but wrong values at most cause an extra call
+to a line hook.
