[GAP Forum] Bug in Add (list function)?

[Benjamin Sambale]

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
