This restores the specific treatment of aggregates that are returned through
an extended return statement in a function returning a class-wide type, and
which was incorrectly dropped in an earlier change.
gcc/ada/
* exp_ch3.adb (Make_Allocator_For_Return): Deal again specifically
with an aggregate returned through an object of a class-wide type.
Tested on x86_64-pc-linux-gnu, committed on master.
