From: Eric Botcazou <ebotca...@adacore.com>
The bug had been present for dynamically allocated objects since the first
rewrite of the finalization machinery more than a decade ago, and was then
propagated to statically declared objects by the recent rewrite.
gcc/ada/ChangeLog:
* exp_util.adb (Finalize_Address): Do not go to the root type for
array types.
Tested on x86_64-pc-linux-gnu, committed on master.
