0a122b
Large integers previously got capped to LLONG_MAX/LLONG_MIN so we could
0a122b
store them as int64_t. This could lead to silent errors occuring.
0a122b
0a122b
Now, we use a double to handle these cases.
0a122b
0a122b
Add a test to confirm that QMPInputVisitor handles this as expected if
0a122b
we're expected an integer value: errors for out of range integer values
0a122b
that got promoted to doubles in this fashion.
