I was thinking that even with the patch 1/2 there is a memory requirements
regression:

If you have a value containing the array (such as $var) it is not lazy.  The
new code will create the memory copies of the intermediate array subsections.
The current FSF GDB code did not.

But in practice I do not think it is a problem as there is already a problem
if one attempts to copy a huge array into an internal variable.  And in most
cases the value is lazy which is OK.


Thanks,
Jan
