<font size="-1">Attached is a archive file (test.gz) containing a<font

<font size="-1"><font size="-1"><font size="-1">Executing
c</font>bc (#2.8.0) on the test.lp</font></font>
file (<i>cbc test.lp</i><font size="-1">) provides the
following result<br>
<font size="-1"><i>Result - Problem proven infeasible</i><i><br>
</i><i>No feasible solution found<br>

the LP file (lines 1258/1259)</font> are swapped,
the same command provides a different result:<br>
<font size="-1"><i>Result - Optimal solution found</i><br>

So, what's wrong with this constraints fle<font

declare constraints?<br>
<font size="-1">Or is this a bug? <font size="-1">A</font>nd,
if so, is there any workaround?<br>
