3 years ago a memory leak in lp solvers was fixed in ticket
[http://trac.sagemath.org/ticket/11917 11917]. It seems that the problems
are back in Sage 6.3. The code
{{{
while True:
P = MixedIntegerLinearProgram(solver="Coin")
}}}
consumes several GB of memory within a few seconds! The same happens with
solver="gurobi", but not with solver="glpk".
Simon King confirmed the leak at [https://groups.google.com/d/msg/sage-
support/dqgmyhMIQdw/qARZHXTt2z8J sage-support], including some analysis
and details.
