Yeah, this was the fix. Thanks, guys!
I found that the the assertion errors I was getting earlier had
something to do with my multithreaded viewer-update code. In normal
use the program has three separate windows showing different views of
a dataset; when the dataset updates I have to update all three
viewers, which I was doing in three separate threads. I guess
something about that isn't quite threadsafe, since while it worked
fine on OSX I had to revert to a sequential update for the Linux port.
Anyway, it's working now!
