Description

_newLp() and _copyLp() creates a completely new CPLEX environment and put the new problem into it.
It should rather go into the same environment.

This ticket is a copy of report #2 of the old bug tracking system. It refers to svn trunk -r2424.

Isn't this question satisfactorily solved by [ed54c0d13df0]?

It is solved in the LP redesign. However, for single thread applications a static CplexEnv? might be better solution than current reference counted.

What would be the advantage of it?

Is't it possible that someone wants to use two environments even in a single thread application? E.g. one may have two problem instances which require different solver settings.
