segmentation and bus errors in different matlab versions

Hello all,

I am having trouble running a couple programs remotely on a super computer that seem to run fine on my laptop for small numbers of iterations.

I have a time simulation program that needs to run for a while taking small time steps. When I test it on my laptop, which is running and older version of Matlab (7.8.0 (R2009a)), it seems to run fine. When I start it remotely (the super computer has version 7.11.0, R2010b) I get a segmentation error after a few iterations.

A similar program does the same thing, but gives be a bus error on the super computer. Neither program is using more than 1% of the computers memory as they run, and as I said, they are fine on my laptop.

I have spend quite a bit of time googling and browsing help forums and can't seem to find an answer. Thanks in advance for any help you many be able to give.

All m-code? Or do you use mex routines? Is this a compiled app?

Sorry,its all in m-code. A .m file that I am calling as a function with workspace variables as inputs.
