Hi David,
this means that an apl value without an owner was detected, but that
no more info about that value is available because the value history was
disable.
The history of a value can be enabled with *./configure
VALUE_HISTORY_WANTED=yes*
or with *make develop*.
If this happens when *)SI *is not clear then there is no need for worries.
Otherwise it would be very valuable to know how to reproduce the stale
value.
Please note that )CHECK normally frees the stale value, so if you do
* )CHECK**
** )SIC**
** )CHECK*
and get a stale value in the first )CHECK but not in the second, then this
does NOT necessarily mean that the stale value was caused by a non-clear
)SI but
that the first )CHECK has dont its job.

I sometimes see output from )CHECK similar to the following:
)check
OK - no stale functions
print_stale_info(): alloc(Cell.cc:119) flags(MC-)
value history disabled
addr=0x1201eb0 ≡1 ⍴⊏7⊐ flags: 0x0C00 MC- Cell.cc:119
OK - no stale values
OK - no stale indices
Is the print_stale_info() output expected, a spurious debug output
that should be removed, or something else?
Let me know if you'd like me to find a minimal test case to make this
happen.
