Although this is easy to code around by checking the length before
calling .Remove, I was surprised this just didn't return silently:

IDL> l=list(1, length=100)
IDL> help,l
L LIST <ID=1424588 NELEMENTS=100>
IDL> l.remove,/all
IDL> help,l
L LIST <ID=1424588 NELEMENTS=0>
IDL> l.remove,/all
% PTR_FREE: Pointer type required in this context: P.
% Error occurred at: LIST::REMOVE
% LIST::REMOVE
% $MAIN$
% Execution halted at: $MAIN$

Passing it along to help the diagnosing of cryptic errors ;)
