From: Eric Botcazou <ebotca...@adacore.com>
This occurs with an instantiation of Ada.Containers.Vectors in a nested
package on an access-to-class-wide type declared with the Put_Image aspect
because of too late a freezing for the internal renaming generated for the
Put_Image procedure.
The change freezes this renaming immediately in this particular case; this
is similar to a trick used in Build_Array_Put_Image_Procedure.
gcc/ada/
* sem_ch13.adb (New_Put_Image_Subprogram): In the nondeferred case
coming from an aspect and for a type with delaying freezing, also
freeze the subprogram immediately.
Tested on x86_64-pc-linux-gnu, committed on master.
