MPS attachment is too big - so you can get files from here:

• https://coral.ie.lehigh.edu/projects/DECOMP/browser/trunk/TempFix/bugs/clpReturnModel.mps.gz
• https://coral.ie.lehigh.edu/projects/DECOMP/browser/trunk/TempFix/bugs/main2.cpp

Note - I tried this with newest release of CLP - same error.

Which version exhibits this? valgrind does not find any errors neither in trunk nor in stable/1.7. For now I'll close the ticket, but please, re-open it if you still experience the problem.

Thanks,
