[SCIP] About Interactive Shell Problem

[朱外明]

Hi Ambros Gleixner,

    Thanks very much for your kind response and advices. 

    Compling with dbg mode is a good suggestion. I have tried but not successed till now. I will try again to make dbg mode workable. 

    Maybe it is a memory problem. Because it is probably that some created objects are not destroyed in time. I would check my program very carefully. I also will use the tool-valgrind as you suggested. 

    Your advices are very helpful. You are so kind. SCIP is really a good tool. Thank you!

    With Best regards!

    Zhu Waiming
