Which directory are you doing "make ztstflop" in? I suspect that what is going on is that the image in question is simply too small to run.

Well, I won't say it's correct but it's about what I'ld expect. What's going on is that you have a system image that is too small for the computation to make any progress. I build such images occasionally for the purpose of testing the checkpointer.

Sorry about botching your name, by the way. I'ld just been responding to someone named Andrew, and experienced a "stuck at" condition.

Thanks for the help, Anthony.
