I have been having the same problem (albeit, I have not run hugin in
about 1 month). Ippei was very helpful to get me going with Xcode, so
I could try to debug it. All I can say is that the program crashes
somewhere in the cross-platform GUI library (sorry, I forgot its
name). The problem is that it is not consistent (we have a case of an
unreliable bug).  It seems to be related to the way the progress is
reported back to the user. Perhaps a way to test this assertion is to
temporarily remove the progress notification code and see if that
"removes" the bug.

In my case, sometimes the optimizer would run, sometimes it would not.
I would have to restart it and try again, until it ran).
