Compiler does not compile valid code?
I was doing some experimenting with Ada.Containers.Multiway_Trees.
However, even the most simple use case, compiling (using gnatmake
test_tree.adb, no switches) and running the following code on Sid,
raises a Program_Error:
raised PROGRAM_ERROR : Tree_Test.Test_Tree.Replace_Element: Position cursor designates root
procedure Test_Tree is
type String_Access is access String;
package Tr is new Ada.Containers.Multiway_Trees
( Element_Type => String_Access );
T : Tree := Empty_Tree;
C : Cursor := Root(T);
T.Insert_Child(Parent => C,
Before => No_Element,
New_Item => new String'("Test"));
I asked in comp.lang.ada, and got confirmation from three other posters
there that this code compiles and runs fine for them, including someone
What am I doing wrong here? Am I forgetting a compiler switch, or is
gnat in Sid broken?
