seems it's by design:

crm_exec_engine.c:786:
...
              if (vht[ret_idx] == NULL)
                {
                  // nonfatalerror 
                  // ("Your call statement wants to return a value "
                  // "to a nonexistent variable; I'll created an "
                  //"isolated one.  Hope that's OK. Varname was",
                  //             outbuf);
...

but the problem is deeper:

$ ./crm114 '-{window; isolate (xxx) //}'

uh? isn't that an illegal varname ? ...

$ ./crm114 '-{window; isolate (xxx) //; output /:*:xxx:\n/}'
Ztart corrupted Zend corrupted  i 3470 len 3 name = -xxx- :xxx:

ah, it is - only that we don't check (anymore) at due time. Did the specs 
change meanwhile?
