Hi,

I seem to have run into a mip bug.

For the attached problem, the LP optimal is 0,
which is confirmed by cplex.  cplex also finds
an integer solution with objective=0.  but glpsol
claims to find an optimal integer solution with
objective=290.

I have a few others similar cases with slightly
different data.  Do you guys want to see the others
as well?

Zewei
