Comment (by tkr):

 I can't replicate this so far. To begin with, the problem solves in less
 than 10 nodes, so the parameter file attached doesn't result in the node
 limit being reached. There is a problem in that the code crashes at the
 very end when freeing the tree if sensitivity analysis is enabled. This
 seems to be an issue with an invalid pointer being left around. when I
 reduce the node limit or try it with other instances, it does, however,
 seem to report finding a solution, even when there is a node limit for all
 the cases I have tried. Of course, if no solution has actually been found
 by the time the node limit is reach, then it report this. I'm assuming you
 checked that a solution had been found and was just not reported.

 I updated your checkout to the most current trunk and re-built it to see
 if that would fix the problem, so it's possible that this made a
 difference, though I can't see why it would. Can you check this with the
 current trunk in your code and see if you're seeing the same thing? I will
 try to track down the source of the crash at the end when sensitivity
 analysis is enabled.
