I have experienced this problem too.  As far as I can tell, in 3.0, structures
are limited to 32Kb.  Also, elements of an array are limited to 32Kb.  Thus the
declaration
  char array[10][33000];
causes wrong code to be generated for references to array.  The problem is,
the compiler uses 16 bit quanitities to remember element sizes.  The code
that gets generated for
   cp=array[i]; 
is the base addresss of array plus i times the sign extended low order
16 bits of 33000!  Very frustrating.  I spent two hours of debugging before
I put the pieces of the puzzle together.
