Infinite recursion:

procedure A is
begin
   A;
end A;

% gnatmake a.adb 
gnatgcc -c a.adb
a.adb:3:04: warning: possible infinite aursion
a.adb:3:04: warning: Storage_Error may be raised at run time
gnatbind -x a.ali
gnatlink a.ali

% ./a
Segmentation fault

Why isn't Storage_Error raised? GNAT 3.13p on GNU/Debian Linux.
