The following should compile quietly:
$ gcc -c p-proc.ads -gnatc
procedure P.Proc is new G;
with Q;
package P is
generic procedure G;
end P;
with System;
with Unchecked_Conversion;
package Q is
generic package Inner_G is
type T is access all Integer;
function Cnv is new Unchecked_Conversion (System.Address, T);
end Inner_G;
end Q;
Tested on x86_64-pc-linux-gnu, committed on trunk
