Thank you for the suggestion!

> Roman, can you give this a shot?

Maybe, we could use the following code:

static int max_mode_int_precision =
  GET_MODE_PRECISION (mode_for_size (MAX_FIXED_MODE_SIZE, MODE_INT, 0));
static int graphite_expression_type_precision = 128 <= max_mode_int_precision ?

128 : max_mode_int_precision;

This allows us to change the size during debugging and avoid using
unacceptable mode size. Tobias, what do you think about this?
