It certainly isn't related to UFSparse, as the Fsparse function only calls the most basic sparse functions of octave. I think you need to supply more information. Which version of octave, what compiler, what platform (is a MAC for example and if so is a big-endian powerpc or a little-endian intel [are they available yet?]), etc? Also helpful would be if you run octave with gdb and give me a backtrace. As well as running octave through valgrind as "valgrind --tool=memcheck octave" and tell me all of the valgrind errors you get (some are expected and are related to readline). Basically, as I can't duplicate this behaviour you'll have to help out quite a bit to debug this behaviour.
