That does rather suggest that it's that method that is causing things to get 
stuck.  Can you share what's inside it?  And when you say "this method works 
fine", do you mean that you've manually tested it with the temp variable that 
goes in before it hangs?

Could it be that whatever printout you're doing of variables like matrix is 
missing some tiny differences -- floating-point rounding errors? -- that are 
responsible for the transformations inside makeTemp or solveTemp behaving 
wrongly and therefore (in the latter case) getting stuck?
