One could edit the routine `emalloc_size' in `malloc.c' to add `sizeof(EIF_NATURAL_64)' to
the size argument so that memory is allocated. Then you should lookup all references to
EIF_Size in the runtime to ensure they also add that memory. One could possible update the
definition of EIF_Size but one has to be careful this is not used for SPECIAL/TUPLEs and
expanded.

Once you have a new runtime, copy all the library files to the EiffelStudio delivery
replacing the standard one.
