[Cbc] Segmentation fault with cbc standalone

[David Ibarra Gómez]

Yep, now it works.
Objective value:                837.63000000
I'll check with a few thousands of problems and chek if everything it's ok.

    Hi David,

    

    Tried with the latest stable  2.8.10, and it appears ok (found an
    optimal solution with obj 837.63000000), could you update your
    version and try again ?

    

    Cheers

      Dear all,
        

        
        I was trying standalone CBC executable using several
          scenarios (several MPS), in this case an small problem. 
        

        
        The context it's linux debian, and acording to the
          following lines:
        

        
        
          Welcome to the CBC MILP Solver
          Version: 2.8.8
          Build Date: May 31 2014
        
        

        
        It's version 2.8.8 (compiled on my machine), I thought
          it was the last stable version
        

        
        Usually everything goes smoothly (much more faster than
          lpSolve, btw), but for a reason that I can't explain I get
          segmentation fault when calling this particular MPS
          (/home/cbc/Cbc-2.8.8/build/bin/cbc
          /tmp/2d5e81e9-c63d-4d0a-9ad5-8196d9d0a37c.mps ).
        

        
        The MPS files are produced with LPSolve (via
          lpSolveAPI, a library to use lpSolve from R, from R code
          embeded with RInside into another C++ executable), and If I
          use that MPS file with LPSolve I get the optimal solution
          (837.63).
        

        
        

        
        Kind Regards
        

        
        David
