I have recently started using explorer. I wrote a module to read data from a
file into a 2D uniform lattice. This lattice and another of the same size
are fed into DisplaceLat which is then fed into LatToGeom. On the first run
everything works fine. But if I then go change the scale in DisplaceLat or
change something in LatToGeom, the latter usually core dumps. I must say that
I am using a big lattice (dims[0] = dims[1] = 300) but the strange thing is
that it used to work a few weeks back. We have, however, installed IRIX 4.0.2
in the meantime, could that be the problem?
I am aware that the problem could be with my module, but after its fired the
first time I usually don't use it again. If I fire LatToGeom more than once
though, it is likely to core dump.

If anybody has any ideas, I would appreciate hearing them.
Thanks
