Dear Forum,
I was fiddling with lists and tried the following, which resulted in a
segmentation fault:
gap> l:=ListWithIdenticalEntries(6,[1,2,3]);;
gap> l[1][1]:=l[3];;
gap> l;
[ [ ~[1], 2, 3 ], [ ~[2], 2, 3 ], [ ~[3], 2, 3 ], [ ~[4], 2, 3 ],
[ ~[5], 2, 3 ],
[ ~[6], 2, 3 ] ]
gap> MakeImmutable(l);
Boom!
I gather that the result of the second assignment is to tie the list
into knots. The following call then goes recursive and eventually
blows the stack (true?).
I thought it worth reporting, in case it's fixable.
Regards,
Justin
