In LambdaMOO version 1.8.1...

 In the file code_gen.c, with BYTECODE_REDUCE_REF
 turned on, you should get a warning (depending on
 your compiler environment) regarding an invalid
 pointer as the fourth arg for qsort on line 1208. I
 believe that this is the correct way to implement the
 qsort comparison function:

 Replace this function (line 1127):

 #ifdef BYTECODE_REDUCE_REF
 static int
 bbd_cmp(int *a, int *b)
 {
 return *a - *b;
 }
 #endif /* BYTECODE_REDUCE_REF */

 With this:

 #ifdef BYTECODE_REDUCE_REF
 static int
 bbd_cmp(const void *a, const void *b)
 {
 return *(int **)a - *(int **)b;
 }
 #endif /* BYTECODE_REDUCE_REF */

 Can anyone confirm this?
