[Bug-glpk] GLPK crash with --intopt option

[Anne-Laurence Putz]

Dear Andrew,

When running the glpsol command line for the MIP model.mps everything is 
OK, optimal solution is found.
But when I launch it with the --intopt option, GLPK crashes (see 
crash.txt file).

It seems that for a column, ipp_tight_bnds() function returns 0, because 
bounds are unchanged, which is not alloweed in reduce_bounds().
Why is it an error ?

I worked with GLP 4.28 on windows XP

Thank you very much for giving me an explanation, and best regards,
