There is a bug in the handling of "ref" arguments .. I don't know
what it is. This procedure:
proc r(x:int, ref y:int)
{
var z = case 1 of (int + long);
print$ y; endl;
y++;
print $y; endl;
}
work fine when not inlined, but it fails when it is inlined.
Generally, a ref parameter x of type t is actually a pointer to t,
and all the uses in the procedure are replaced by *x, that is,
automagically dereferenced. The argument must be a pointer,
for example:
var x = 1;
r(x, &x);
When inlined, it is exactly the same EXCEPT that if the argument
is the address of a simple variable, the uses are replaced by the
variable. This no longer works ..
