[Coin-discuss] CoinMpsIO -- LI Bounds problem?

I have the most recent version of COIN, I believe. I nevertheless have
trouble reading some mps files. This is similar to Anureet's problem
a few weeks ago. When reading the file

splittable.flow.network.design/ns25/pr3.mps

from the collection arcset.data.mps.gz available from

http://ieor.berkeley.edu/~atamturk/data/arcset/

using:

   OsiClpSolverInterface *clp = new OsiClpSolverInterface;
   clp->readMps(name, "mps");


I get:

Coin0001I At line 1 NAME          pr3
Coin0001I At line 2 ROWS
Coin0001I At line 2214 COLUMNS
Coin0001I At line 36804 RHS
Coin0001I At line 36990 BOUNDS
Coin3006W No match for column C8541     0 at line 45531 <  LI BOUND     C8541  0 >
Coin3006W No match for column C8542     0 at line 45532 <  LI BOUND     C8542  0 >
Coin3006W No match for column C8543     0 at line 45533 <  LI BOUND     C8543  0 >
Coin3006W No match for column C8544     0 at line 45534 <  LI BOUND     C8544  0 >
Coin3006W No match for column C8545     0 at line 45535 <  LI BOUND     C8545  0 
...


and then a crash. Does CoinMpsIO support these LI bounds or not? What change 
should I make to read these files with OsiClp?
