Try running RHIDE from DOS so that you use the CWSDPMI.  Your program
will crash at the point that the exception occours, look at your call
stack for the function that caused the error.  In that function you
likly find an un-initilised/wrongly set pointer or that you writing
past the memory allocated to a pointer/array.
