Interesting...  did you use the same binary on both Bob's emulator and Ersatz?

Ah, I meant to mail that to the list.  No matter, it got to where it was most

I'd suggest you recompile factor if you have the source, but add some
debugging. If you can't do that, you could try running it with adb (the
debugger, man 1 adb for details).
