[Bug-glpk] glpsol: crash on display

[Daniel Franke]

Hi,

no idea if the MathProg statements below are legal.
However, I'm sure the solver should not crash :)

$> cat segfault.mod
set samples dimen 4;

set bnodes := (setof{(sid, bid, temp, rep) in samples: bid !in bnodes} bid);
display bnodes;

data;
set samples :=
        # sid  bid  temp  rep
        (  A,   Z,   10,   1 )
        (  B,   Z,   10,   1 )
        (  C,   Z,   20,   1 )
        ;
end;

$> glpsol --math segfault.mod
