Dear GAP Forum,

consider this small GAP code (I hope it is minimal somehow):

L:=[];
e:=[1];
for s in [[1],[0]] do
 e[1]:=s[1];
 Add(L,e);
od;

After that the list L should be [ [ 1 ], [ 0 ] ]. However GAP gives [ [ 0 ], [ 0 ] ]. I'm not quite sure if this is a bug. It seems to me that the Add function only adds a pointer or something similar. Note that the code works as expected if one uses e:=1 and so on (without additional square brackets). By the way I'm using GAP 4.4.12.

Thanks for clarification,
Benjamin Sambale
