[Clp] Infinite loop in Clp

[William H. Patton]

>>Is there a way to see what coin rescales my problem to?
I see in clp\src
presolveToFile  controlled by param parser
	    case PRESOLVE:
	      if (action==0)
		preSolve = 5;
	      else if (action==1)
		preSolve=0;
	      else if (action==2)
		preSolve=10;
	      else
		preSolveFile=true;
	      break;
and
	      solveOptions.setSolveType(method);
	      if(preSolveFile)
		presolveOptions |= 0x40000000;
	      solveOptions.setSpecialOption(4,presolveOptions);

	bool presolveToFile = (presolveOptions&0x40000000)!=0;

I expected Coin to be able to rescale my problem for me, but that
might be a misunderstanding?

I believe that my problem should be possible to rescale even though it
has very large and very small numbers, they should be grouped together
such that rescaling should be possible.

Is there a way to see what coin rescales my problem to?
