You rang? :)

Why do you think it's file related?

good.
    

Note that the "RP" below "imem_protection" indicates that the
process had tried to branch to RP=a.0000001c, which is not a valid
code address.  This usually indicates that someone corrupted the
stack, and then tried to exit through the corrupted stack marker.

When I enounter dumps like this, I look at the registers in use at the
time of the trap (lev 0,1 ; dr) and try to determine where we were.
(Registers r2 and r31 can be useful clues, sometimes showing where we
were recently.)

That said, stack corruption aborts are sometimes quite hard to
debug.  

As a general principle, I'd ask "are you on the current version of Speeware",
and if not: try upgrading to it and see if the problem goes away.
